- Coal-water mixtures and coal-tar mixtures have been found interesting for a variety of reasons, essentially concerning cost, quality and availability. (google.com)
- Where coal-tar mixtures are concerned, one limitation to date has been the fact that when the coal content of the mixture exceeds 40% by weight, the apparent viscosity of the mixture increases very rapidly, with the result that at about 50% solids (by weight) the mixture is no longer pumpable. (google.com)
- Contrary to what has been reported on the state of the art, however, it has been found surprisingly that a given coal grain-size distribution permits production of coal-tar mixtures containing more than 50% coal and having a viscosity such as to render the mixture easily pumpable and injectable, and without any marked variations with time. (google.com)
- Furthermore, above 40% solids (by weight) the apparent viscosity of the coal-tar mixture also increases markedly with time. (google.com)
