If you can imagine a future powered by sustainable food and fuels; if you can imagine a future where globalism means that appropriate technologies are employed where they work best to the globes greatest advantage; if you can imagine a future of cooperation and collaboration to work out humankinds tensions, then you see a future envisioned by Advanced Biofuels USA.. The future of the advanced biofuels industry is at a critical crossroads. In the US, the Renewable Fuel Standard has created a demand of 15 billion gallons/year of corn ethanol, an amount which covers about 10% of the US market and provides renewable octane by replacing carcinogenic MTBE. US and Brazilian sources have filled this demand. However, the US seems stuck on the 15 billion/year plateau providing no meaningful demand for advanced motor vehicle biofuels. Even the Renewable Fuel Standard (RFS) has little impact since it has not been used by the government to push for more investment in advanced biofuels. Once corn ethanol ...

Current public focus on reduction of the use of fossil fuels and replacement of these fuels with cleaner-burning renewable fuels has played a key role in the growth of the fuel ethanol industry. Large demand for blending ethanol into gasoline began with its use as an oxygenated gasoline additive. Currently the US EPA has set the denatured ethanol-to-gasoline blend rate at 10 percent, but discussions are being held to increase this level to 15 percent or higher. Automotive companies are also producing flex-fuel vehicles; able to operate on ethanol-to-gasoline blends of up to 85 percent denatured ethanol, called E85.. With all this increased attention to fuel ethanol, producers and blenders have increased awareness of mandated fuel ethanol specifications, outlined in ASTM D4806 - Specification for Denatured Fuel Ethanol for Blending with Gasoline for Use as Automotive Spark-Ignition Engine Fuel.. Ethanol producers are required by law to render the fuel ethanol unfit for human consumption by adding ...
A new poll found that Iowans overwhelmingly oppose waivers given by EPA to oil refiners allowing them to ignore their obligations to blend renewable fuels like ethanol under the Renewable Fuel Standard (RFS). The poll also found Iowa voters strongly support the RFS and use of renewable fuels. By a margin of nearly 2-to-1, Iowans said they oppose RFS waivers, and more than four out of five respondents expressed a favorable opinion of renewable fuels and support for the RFS.. Eighty-six percent of Iowa voters have a favorable opinion of renewable fuels, and eighty-one expressed support for the RFS, according to a poll conducted by Morning Consult, a Washington DC polling and news site.. Under the Trump administration, the number of waivers for oil companies has grown so dramatically that almost one-third of all oil refineries in the country have recently been exempted from the requirements of the RFS. As a result of these waivers and the effects of COVID 19, more than 130 renewable ethanol plants ...

An item of interest to ethanol producers and other supporters of ethanol is this announcement by EPA, as further clarified by this announcement by EERE: The U.S. Environmental Protection Agency (EPA) announced on November 17 that the 2009 renewable fuel standard (RFS) will require most refiners, importers, and non-oxygenate blenders of gasoline to displace 10.21% of their gasoline with renewable fuels such as ethanol. That requirement aims to ensure that at least 11.1 billion gallons of fuels will be sold in 2009. . . . While the RFS requirement is increasing by about 23%-from 9 billion gallons in 2008 to 11.1 billion gallons in 2009-the percentage requirement is increasing by nearly one third, from 7.76% in 2008 to 10.21% in 2009. The larger relative increase in the percentage requirement reflects the fact that fuel consumption is expected to be lower in 2009, so a greater percentage of renewable fuel is needed to reach 11.1 billion gallons of renewable fuels. ....

Seven biofuel organizations intervened yesterday in support of U.S. EPA in a petroleum industry-backed legal challenge to a requirement to blend more sustainable biofuels into gasoline, saying the agency should maintain the authority in setting targets.. The Advanced Biofuels Association, the Advanced Ethanol Council, the American Coalition for Ethanol, the Biotechnology Industry Organization, Growth Energy, the National Biodiesel Board, and the Renewable Fuels Association assert that EPA has based its requirements on projections made by the Energy Information Administration, as well as additional information from private companies.. Precedent makes clear that EPA can adopt standards calculated to spur development, consistent with Congresss express statutory objectives, states the intervenors brief.. The American Petroleum Institute (API) filed suit in July, claiming EPA is subjecting gasoline blenders to an unreasonably high requirement to mix 8.65 million gallons of cellulosic biofuels ...
Among various plant-derived biomass, starch and sugar crops are recognized as major feedstock for the first generation of biorefinery, whereas lignocellulosic biomass is regarded as the feedstock for the second generation. This chapter reviews primarily aspects of production, processing technology, and uses of industrial sugar and starch crops, as well as the future of these crops for biorefinery. The use of sugar crops (sugar cane, sugar beet, sweet sorghum) as the feedstock in biorefinery has a greater advantage in terms of crop reproduction and the conversion process over the starch crops. The major sources of starch crops for biorefinery include cereal grains (corn, wheat, and rice) and roots and tubers (potato and cassava). Either the use of sugar or starch crops individually can be achieved in biorefinery, but the integration of sugar- and starch-based biorefinery production can significantly improve the overall process economics and commercialization. ...
TY - BOOK. T1 - Process design, supply chain, economic and environmental analysis for chemical production in a glycerol biorefinery: Towards the sustainable design of biorefineries. AU - Loureiro da Costa Lira Gargalo, Carina. PY - 2017. Y1 - 2017. N2 - Drivers such as our deep dependence on fossil fuels availability and price volatility, global concern about climate change and social distress, are steering the economy to be more sustainable and based on a greater use of renewable resources. Therefore, the concept of integrated biorefineries has attracted much attention by aspiring at replacing fossil sources. However, as has been recently witnessed through multiple failures and the shutdown of biorefinery plants all over the world, a biobased economy that heavily depends on the production of biofuels, leads to unsatisfactory results. Thus, it seems that an economy based on the innovative and cost-efficient use of bio-resources for the production of both chemicals and biofuels/bioenergy, is in ...
Several years ago, a war of words erupted between renewable fuel advocates and petroleum interests over the cost of E15 conversions, promoting a 2013 Petroleum Equipment Institute study that was widely hailed in renewable fuel circles.. At the time, the Renewable Fuels Association had this to say:. The cost of upgrading an existing retail gas station to sell E15 is substantially less than recently suggested by ethanol opponents, according to new information from the Petroleum Equipment Institute (PEI).. E15 has now been in the marketplace for over a year, and those stations offering E15 have seen increases in both overall fuel sales and in-store sales. Unfortunately, some of the retailers wanting to explore E15 have been discouraged from doing so by biofuel opponents who hope to block widespread use of the new fuel blend. Those detractors have stated that adding E15 will cost retailers $200,000 to $300,000. The ethanol industry has repeatedly stated that such estimates represent an absolute ...
Biogas production from organic materials can be used as a renewable vehicle fuel, provide heat and generate electricity and can thereby reduce the greenhouse gas emissions. This thesis focuses on the biogas production based on lignocelluloses. There is an abundant availability of lignocelluloses, constituting 50% of the total biomass worldwide. However, the biomass recalcitrance limits the microbial degradation as well as the biogas production from these types of materials. In the present work different pretreatment methods have been performed in order to decrease the biomass recalcitrance and improve the biogas production. Steam explosion pretreatment, together with the addition of sodium hydroxide and hydrogen peroxide, has been performed on lignocellulosic-rich paper tube residuals. The pretreatment has resulted in methane yields of up to 493 NmL/gVS, which is an increase by 107% compared with untreated material. Furthermore, the use of an organic solvent, N-methylmorpholine-N-oxide (NMMO), ...
Biobased and Renewable Products Advocacy Group (BRAG®). Overview:. Biobased chemicals and biofuels are steadily taking root thanks to both popular appeal and political support. The consumer and political goals of reducing Americas dependence on foreign oil, enhancing national security, and greening the economy converge in biobased chemicals and advanced biofuels, the promising technology of producing commercial chemicals and fuels from renewable resources. With Congresss commitment to advanced biofuels found in the 2007 Energy Independence and Security Act, compelling incentives to invest in and support growth of biotechnologies has spurred record production. Some estimate biobased chemicals share of the global chemical industry will grow from 2 percent to 22 percent by 2025.. Much of the growth in biofuels technology development has been driven by the fuel-blending requirements set in the U.S. Environmental Protection Agencys (EPA) Renewable Fuel Standard (RFS). But the RFS, along with ...
Fatty acid-derived biofuels can be a better solution than bioethanol to replace petroleum fuel, since they have similar energy content and combustion properties as current transportation fuels. The environmentally friendly microbial fermentation process has been used to synthesize advanced biofuels from renewable feedstock. Due to their robustness as well as the high tolerance to fermentation inhibitors and phage contamination, yeast strains such as Saccharomyces cerevisiae and Yarrowia lipolytica have attracted tremendous attention in recent studies regarding the production of fatty acid-derived biofuels, including fatty acids, fatty acid ethyl esters, fatty alcohols, and fatty alkanes. However, the native yeast strains cannot produce fatty acids and fatty acid-derived biofuels in large quantities. To this end, we have summarized recent publications in this review on metabolic engineering of yeast strains to improve the production of fatty acid-derived biofuels, identified the bottlenecks that ...

Biofuels are the most awaited products of scientific research. The fossil fuels are being exhausted, and pollution is increasing globally. Algal biofuels are one of the promising options. They are wonderful tiny factories that yield a variety of substances that have the property to act as sources of ecofriendly fuels. More attention has been focused on microalgae-derived biomass for generating diverse renewable energy sources. The distinct features that microalgae possess include high biomass yield, abundant oil content, no requirement for land and easy cultivation in wastewaters coupled with carbon dioxide mitigation. Microalgae are tiny reservoirs of a plethora of biofuels. The diverse algal biofuels range from biodiesel, straight vegetable oil (SVO), lipids, ethanol and hydrogen. Biofuels are the need of today, and researchers around the globe are exploring the options for biological fuel production.
Engineered strains of Saccharomyces cerevisiae have significantly improved the prospects of biorefinery by improving the bioconversion yields in lignocellulosic bioethanol production and expanding the product profiles to include advanced biofuels and chemicals. However, the lignocellulosic biorefinery concept has not been fully applied using engineered strains in which either xylose utilization or advanced biofuel/chemical production pathways have been upgraded separately. Specifically, high-performance xylose-fermenting strains have rarely been employed as advanced biofuel and chemical production platforms and require further engineering to expand their product profiles. In this study, we refactored a high-performance xylose-fermenting S. cerevisiae that could potentially serve as a platform strain for advanced biofuels and biochemical production. Through combinatorial CRISPR-Cas9-mediated rational and evolutionary engineering, we obtained a newly refactored isomerase-based xylose-fermenting strain,
Biomass is a crucial energy resource used for the generation of electricity and transportation fuels. Microalgae exhibit a high content of biocomponents which makes them a potential feedstock for the generation of ecofriendly biofuels. Biofuels derived from microalgae are suitable carbon-neutral replacements for petroleum. Fermentation is the major process for metabolic conversion of microalgal biocompounds into biofuels such as bioethanol and higher alcohols. In this review, we explored the use of all three major biocomponents of microalgal biomass including carbohydrates, proteins, and lipids for maximum biofuel generation. Application of several pretreatment methods for enhancement the bioavailability of substrates (simple sugar, amino acid, and fatty acid) was discussed. This review goes one step further to discuss how to direct these biocomponents for the generation of various biofuels (bioethanol, higher alcohol, and biodiesel) through fermentation and transesterification processes. Such an

Extensive native Jatropha curcas L. (Jatropha) crop areas have been planted in Central America marginal lands since 2008 as a non-edible prospective feedstock alternative to high-value, edible palm oil. Jatropha biodiesel is currently exclusively produced in the region at commercial scale utilizing alkaline catalysts. Recently, a free, soluble Thermomyces lanuginosus (TL) 1,3 specific lipase has shown promise as biocatalyst, reportedly yielding up to 96 % ASTM D6751 compliant biodiesel after 24 h transesterification of soybean, canola oils and other feedstocks. Biodiesel conversion rate and quality of enzymatically catalyzed transesterification of Jatropha oil was evaluated. Two lipases: free, soluble TL and immobilized Candida antarctica (CA) catalyzed methanolic transesterification of crude Jatropha and refined palm oil. Jatropha yields were similar to palm biodiesel with NaOH as catalyst. After 24 h transesterification, Jatropha (81 %) and palm oil (86 %) biodiesel yields with TL as catalyst were

Biodiesel is typically derived from vegetable oil, but can also be derived from animal oils (lard and tallow). The most common feedstock for biodiesel production facilities in Missouri is soybean oil from the Missouri soybean crop. Biodiesel can also be derived from other vegetable sources such as rapeseed, corn, cottonseed and peanut; animal sources, such as tallow or lard; and waste cooking oils (yellow grease).. Biodiesel production plants in Missouri process raw soybean oil into a form suitable for use in diesel engines. Various extraction processes exist for converting raw soybean oil to biodiesel, but the most common commercial-scale facilities use 100 pounds of soybean oil and 10 pounds of methanol mixed with a catalyst. This results in 100 pounds of neat biodiesel and 10 pounds of glycerin. Glycerin is the primary byproduct or coproduct of biodiesel production and has value when further refined for other markets.. Raw or refined vegetable oil, or recycled greases that have not been ...
Advanced biofuels, also known as second generation, were supposed to provide the answer. They are produced from waste products such as animal manure and bio-waste or agricultural by-products that are not fit for human or animal consumption, such as grape stalks, nut shells, and corn cobs.. Since there is no food or feed application for these products, their use in biofuel production should not compete with food production, the thinking goes.. The case of molasses. But the latest version of the Commissions proposal included an agricultural product which does not fit this criterion: molasses, a thick and sticky liquid sourced from sugarcane or sugar beets during the sugar refining process.. Molasses are the primary ingredient in yeast, which is used to make bread, wine and beer. They are also used in confectionery (chocolate bars, candies and biscuits), and feed to animals. Indeed, the EU lists them as feed material alongside corn and soy.. Molasses are our primary ingredient; it is a fresh ...
Notes: Domestic crude oil production includes lease condensate and is estimated using a combination of short-term forecasts for the lower 48 states and the latest available production estimates from Alaska. Beginning with data for the week ending June 1, 2018, weekly crude oil production estimates are rounded to the nearest 100,000 b/d at the U.S. and lower 48 state levels. Finished motor gasoline production and product supplied includes a weekly adjustment applied only to the U.S. total to correct for the imbalance created by blending of fuel ethanol and motor gasoline blending components. From 1993 to June 4, 2010, this adjustment was estimated from the latest monthly data and allocated to formulation and PAD District production data. Reformulated and conventional gasoline production excludes adjustments for fuel ethanol and motor gasoline blending components. Historical data prior to June 4, 2010 includes the adjustment allocated by PAD District formulation. Propane/propylene includes ...

Biodiesel production from microalgae is being widely developed at different scales as a potential source of renewable energy with both economic and environmental benefits. Although many microalgae species have been identified and isolated for lipid production, there is currently no consensus as to which species provide the highest productivity. Different species are expected to function best at different aquatic, geographical and climatic conditions. In addition, other value-added products are now being considered for commercial production which necessitates the selection of the most capable algae strains suitable for multiple-product algae biorefineries. Here we present and review practical issues of several simple and robust methods for microalgae isolation and selection for traits that maybe most relevant for commercial biodiesel production. A combination of conventional and modern techniques is likely to be the most efficient route from isolation to large-scale cultivation.
Bio-based Chemical Production from Arundo donax Feedstock Fermentation using Cosenzaea myxofaciens BPM1. Valeria Ventorino,a Alessandro Robertiello,a Sharon Viscardi,a Annamaria Ambrosanio,aVincenza Faraco,b and Olimpia Pepe a,*. Bio-based organic acids are an eco-friendly alternative to petroleum-derived products. In this work, the production of organic chemicals was investigated for the first time in the Cosenzaea myxofaciens species using hydrolysed lignocellulosic biomass from Arundo donax. The strain C. myxofaciens BPM1, isolated from bovine rumen, was able to produce a high amount of lactic acid, followed by acetic and succinic acids in synthetic substrate in microaerophilic and anaerobic conditions. When hydrolysed lignocellulosic biomass from Arundo donax supplemented with several nitrogen sources was used as substrate in separate hydrolysis and fermentation in anaerobic conditions, a significant increase in organic acids was recovered, reaching values up to 12.13 ± 0.17, 1.68 ± 0.1, ...
EPA Approves Grain Sorghum Pathway - The Environmental Protection Agency (EPA) announced yesterday it has approved grain sorghum as an eligible feedstock under the Renewable Fuel Standard (RFS). National Sorghum Producers (NSP) has worked closely with EPA for about three years in getting grain sorghum listed as an advanced biofuel feedstock, and the feat has finally been won. The RFS requires a certain amount of feedstocks to be used to produced advanced biofuels. With sorghums listing, it will now create a significant amount of domestically-grown sorghum that needs to be used to produce ethanol. This use, in turn, will add value and profitability to the producers crop. This gives an incentive to the ethanol plants to use sorghum when producing their biofuels. EPA found that, when plants use sorghum to create ethanol at facilities that use natural gas, they have a greenhouse gas (GHG) emissions reduction of 32 percent, qualifying it as a conventional ethanol. NSP expects at least one existing ...

An apparatus for enzymatic hydrolysis and fermentation of pretreated lignocellulosic material, in the form of a tower bioreactor, having mixers to achieve intermittent mixing of the material. Precise
The demand for cellulosic biofuels is on the rise because of the anticipation for sustainable energy and less greenhouse gas emissions in the future. However, production of cellulosic biofuels, especially cellulosic butanol, has been hampered by the lack of potent microbes that are capable of converting cellulosic biomass into biofuels. We report a wild-type Thermoanaerobacterium thermosaccharolyticum strain TG57, which is capable of using microcrystalline cellulose directly to produce butanol (1.93 g/liter) as the only final product (without any acetone or ethanol produced), comparable to that of engineered microbes thus far. Strain TG57 exhibits significant advances including unique genes responsible for a new butyrate synthesis pathway, no carbon catabolite repression, and the absence of genes responsible for acetone synthesis (which is observed as the main by-product in most Clostridium strains known today). Furthermore, the use of glucose analog 2-deoxyglucose posed a selection pressure to ...
Crude glycerol is a main by-product from biodiesel production, and efficient utilization of crude glycerol will bring significant economic and environmental benefits. However, the complex compositions of crude glycerol may impair the cellular growth and inhibit the crude glycerol consumption. Therefore, it is necessary to find a simple method to treat the crude glycerol and release the inhibition on cell metabolism. The simply purified crude glycerol by activated carbon can be used as the carbon source to produce succinate in two-stage fermentation by the engineered Escherichia coli strain, MLB (ldhA−, pflB−) expressing phosphoenolpyruvate carboxykinase. In the flask experiments, succinate production from crude glycerol without treatment was less than that from pure glycerol. However, in the experiments of 1.5-L bioreactor, little succinate was produced in crude glycerol. The simply purified crude glycerol was used as carbon source for succinate production, and the glycerol consumption and succinate

Robert, a well educated and well respected Chem Eng., is again writing for the general public. Unfortunately, he, along with most of the authors of such articles, bundle biofuels together such that the reader after cruising through their words of wisdom still has little insight or understanding of the radical differences - pro or con - between the various biofuel sources. This actually makes his article totally moot.Lets break it down:Ethanol from any feedstock requires a 100% volume - high energy distillation process, is an incredibly caustic and toxic fuel, generates high volumes of undesirable emissions, the common feedstock (corn, switchgrass, …) offer little CO2 processing, the fuel demonstrates an extreme evaporation rate, has a relatively low BTU density, is not now, nor will likely become cost viable even against petroleum in the near future. Yet, corn for ethanol production now occupies 48 million acres of prime U.S. farmland. Ethanol as we know it today should simply be discarded ...
Crude glycerol represents ca. 10 % of the product output in biodiesel production. As the biodiesel production increases exponentially, the amount of resulting crude glycerol is extensively high. The problem of its disposal or effective utilization is of increasing importance. In this work, the composities of poly(vinyl alcohol), horn meal and crude glycerol with the mass ratios of crude glycerol and poly(vinyl alcohol) 0.75, 1.5 and 2.25 were prepared and used for the formation of mulching coatings. The influence of the addition of crude glycerol to the composites on the mechanical, viscoelastic properties, swelling and dimensional stability in water of the composite films was examined. The increase of the amount of glycerol resulted in the increase of elasticity and dimensional stability of the composite films. The effect of the mulch films containing the different amount crude glycerol on evaporation of water from the substrate, vegetation of plants, soil properties and weeds (wild mustard and ...

Ethyl ester biodiesel has been produced from a non-edible Jatropha curcas oil. Oil was extracted from the plant seed using n-hexane at 60°C and pretreated by alkaline refining process to reduce the free fatty acid level to less than 1%. Base-catalysed transesterification reaction with absolute ethanol using potassium hydroxide catalyst was adopted for the conversion. Various physicochemical properties of the refined Jatropha curcas oil were investigated. The ethyl ester biodiesel produced was characterised for its fuel properties such as specific gravity at 15°C, flash point, pour point, kinematic viscosity, cetane number, iodine value and higher heating value using American Society for Testing and Materials Standard Methods. The crude and refined Jatropha curcas oil yields were 58.16% and 52.5%. The physicochemical analysis revealed FFA, saponification value and peroxide value of refined Jatropha curcas oil to be 0.58 mg KOH/g, 159.9 and 1.92 m E/kg respectively. The fatty acid composition obtained
Biodiesel and hydrotreated vegetable oil (HVO) are currently viewed by the transportation sector as the most viable alternative fuels to replace petroleum-based fuels. The use of biodiesel has, however, been limited by the deteriorative effect of biodiesel on rubber parts in automobile fuel systems. This work therefore aimed at investigating the degradation of acrylonitrile butadiene rubber (NBR) and fluoroelastomers (FKM) on exposure to biodiesel and HVO at different temperatures and oxygen concentrations in an automated ageing equipment and a high-pressure autoclave. The oxidation of biodiesel at 80 °C was promoted by an increase in the oxygen partial pressure, resulting in the formation of larger amounts of hydroperoxides and acids in the fuel. The fatty acid methyl esters of the biodiesel oxidized less at 150 °C on autoclave aging, because the termination reactions between alkyl and alkylperoxyl radicals dominated over the initiation reactions.

Bioconversion of different organic waste materials to hydrogen is a sustainable technology for hydrogen production and it has been investigated by several researchers. Crude glycerol generated during biodiesel manufacturing process can also be used as a feedstock for hydrogen production using microbial processes. The possibility of using crude glycerol as a feedstock for biohydrogen production has been reviewed in this article. A review of recent global biodiesel and crude glycerol production and their future market potential has also been carried out. Similarly, different technical constraints of crude glycerol bioconversion have been elaborately discussed and some strategies for improved hydrogen yield have also been proposed. It has been underlined that use of crude glycerol from biodiesel processing plants for hydrogen production has many advantages over the use of other organic wastes as ...
Lignin, a complex aromatic polymer in terrestrial plants, contributes significantly to biomass recalcitrance to microbial and/or enzymatic deconstruction. To reduce biomass recalcitrance, substantial endeavors have been exerted on pretreatment and lignin engineering in the past few decades. Lignin removal and/or alteration of lignin structure have been shown to result in reduced biomass recalcitrance with improved cell wall digestibility. While high lignin content is usually a barrier to a cost-efficient application of bioresource to biofuels, the direct correlation of lignin structure and its concomitant properties with biomass remains unclear due to the complexity of cell wall and lignin structure. Advancement in application of biorefinery to production of biofuels, chemicals, and biomaterials necessitates a fundamental understanding of the relationship of lignin structure and biomass recalcitrance. In this mini-review, we focus on recent investigations on the influence of lignin chemical properties

We asked our leaders their thoughts on which next generation feedstocks they thought would be the most promising in 2012. The responses were fairly evenly split among municipal solid waste (MSW at 26%), Nonfood energy crops (such as camelina and jatropha at 24% and algae (at 20%). Cellulosic trailed slightly at about 17%.. The prominence of MSW suggesting that not only is waste ideal because it reduces landfill demand, methane gases and is a low cost feedstock, but also likely because of promising advances in technology and commercialisation from companies such as Enerkem and Fulcrum Bioenergy. Although waste gas did not perform well (8 %), we consider that to be in the same general category, and with companies like LanzaTech launching pilot plants later this year, this category could come into play.. Close on the heels of MSW are the non-energy feedstocks like jatropha and camelina - the latter which has received significant testing and use by the US military and commercial airlines. Many ...
Author: Rameshprabu Ramaraj, Rungthip Kawaree, Yuwalee Unpaprom. Category: [Download PDF]. Abstract:. Microalgae biodiesel are reported to be better than fossil fuels in terms of life-cycle energy performance. Green alga, Botryococcus braunii symbolizes one of the most favorable resources of biodiesel due to relatively high lipid content. The present study focused on the cultivation of Botryococcus braunii with the fed-batch in 4 L lab-scale continuously stirred tank reactors (CSTRs) through inexpensive red Nile tilapia effluent medium (RNTEM), biomass growth, protein, carbohydrate, lipid, hydrocarbon production and fatty acids profiles. Additionally, in this study we have evaluated the feasibility of biodiesel production directly from B. braunii biomass at laboratory scale achieved through direct transesterification process. B. braunii growth confirmed the highest biomass yield (8.57 g L?1) and 35.32% hydrocarbon content was observed. Further, 47.59% lipids, 16.39% proteins and 38.21% ...
In this paper, two kinds of different biodiesel were tested in terms of their impact on wear resistance of Si-DLC coated 100Cr6 flat worn by an oscillating 100Cr6 ball. The knowledge about the tribological behaviour of different types of biodiesel is rare. Rape and soybean are two of the most common natural sources for biodiesel production. Also, if the quality of biodiesel seems to be similar and, according to the demands, biodiesel from different natural origin could affect changes in the tribological behaviour. Although, soybean methyl ester (SME) gives the best results at room temperature wear tests, 150°C SME reaches wear rates of Si-DLC flat against 100Cr6 ball almost double as high as rapeseed methyl ester (RME). It is evident that, with increasing fraction of oxidation stabilizer C|sub|23|/sub|H|sub|32|/sub|O|sub|2|/sub|, the wear rate increases. For silicon doped hydrogenated diamond-like carbon is especially suitable, for use in biodiesels, where certain fraction of humidity, dissociated
Latin America is emerging as a key global producer of biofuels as nations across the region seek to use competitive advantages such as fertile land and tropical weather to tap into unprecedented energy prices. The region invested more than $8 billion in biodiesel and ethanol in 2007 and has already launched new projects that could increase global energy production as demand from emerging-market economies outstrips growth in oil and gas production. The efforts contrast sharply with the broad condemnation by leaders in the region, led by Venezuelas Hugo Chavez, that the fuels increase food prices and spur global hunger. Critics around the world have echoed such concerns, charging farmers may divert crops toward biofuels and away from food crops. A biofuels push could sustain energy flows from Latin America toward the United States, the worlds top energy consumer, as falling oil output in Venezuela and Mexico has left Washington seeking new supplies in other regions. Analysts say Latin Americas soil and

Citation: Saha, B.C., Cotta, M.A. 2014. Fuel ethanol production from alkaline peroxide pretreated corn stover [abstract]. American Society for Microbiology. Poster No. 2250. Interpretive Summary: Technical Abstract: Corn stover (CS) has the potential to serve as an abundant low-cost feedstock for production of fuel ethanol. Due to heterogeneous complexity and recalcitrance of lignocellulosic feedstocks, pretreatment is required to break the lignin seal and/or disrupt the structure of crystalline cellulose to increase the accessibility of cellulolytic enzymes. Alkaline peroxide pretreatment (AHP) is known to delignify agricultural residues, with concomitant increase in saccharification efficiency. Milled CS (10%, w/v) was slurried in water containing 2% (v/v) H2O2 and adjusted to pH 11.5 using 10 M NaOH and shaken in an incubator at 250 rpm at 35 oC for 24 h, unless otherwise specified. The enzymatic hydrolysis of the AHP pretreated CS was performed by shaking slowly (100 rpm) at 45 oC for 72 h ...
Ten years ago this month, President George W. Bush signed the Renewable Fuel Standard into law, implementing regulations that require companies to blend specific amounts of renewable fuels into gasoline. No state benefits more from the RFS than Iowa, and with the Iowa caucuses six months away, presidential candidates are already pandering, flip flopping, or avoiding the issue altogether as they attempt to woo voters.. While Iowa farmers who grow corn specifically for biofuels have greatly benefited from the RFS, ethanol and other biofuels are overwhelmingly hurting the planet and peoples pocketbooks. This crop of presidential candidates needs to keep that in mind as they continue to canvass the Hawkeye State.. Its easy to see why politicians pander to Iowans. The last two Republicans to win the Iowa caucus, Mike Huckabee and Rick Santorum, both supported the RFS. Candidates that have opposed the RFS-like Marco Rubio, Bobby Jindal, and Rand Paul-have avoided the issue in Iowa, skipping ...
Celulose, hemiceluloses e lignina são os três principais componentes da biomassa. Esses componentes foram detalhadamente estudados e explorados com o objetivo de se alcançar o modelo de biorrefinaria. Celulose e hemiceluloses foram extraídas da madeira de Eucalyptus urograndis enquanto a lignina foi extraída dessa mesma espécie e de outras três espécies de folhosas (Eucalyptus globulus, Eucalyptus nitens, Populus trichocarpa). Celulose nanofibrilada (NFC) foi modificada usando TEMPO e hidroxiapatita (HAp) e posteriormente usada para produzir aerocelulose através de secagem direta por liofilização. A morfologia dos aerogéis de celulose oxidados mostraram uma distribuição homogênea no tamanho dos pores. Tal distribuição foi mantida após adição de HAp. Aerogels de celulose modificada também apresentaram-se mais resistentes a pressão que os seus correspondentes não modificados. Xilanas foram usadas tanto como aditivos na polpa celulósica como para produção de materiais com ...
