Solvent refining of coal
Refined coal is the product of the coal-upgrading technology that removes moisture and certain pollutants from lower-rank coals such as sub-bituminous and lignite (brown) coals, raising their calorific values. Coal refining or upgrading technologies are typically pre-combustion treatments and processes that alter the characteristics of coal before it is burned. Pre-combustion coal-upgrading technologies aim to increase efficiency and reduce emissions when coal is burned.

WebWe are exploring thermochemical routes for converting biomass to fuels and chemicals. For instance, we are exploring the production of bio-oil by dissolving lignocellulose in various solvents, e.g. a fraction of the bio-oil product or a refinery stream. We are also exploring the production of chemical intermediates from bio-based platform ... WebA process is provided for the production of solvent refined coal, which comprises heating the coal while slurried in a solvent under hydrogenation conditions to substantially liquefy the coal followed by a step of separating the non-dissolved solids from the solution, e.g. by filtration, improved by the feature that a small percentage of the liquefiable matter of the …
