Refined coal - Wikipedia

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