An improved process for converting coal to liquid and gaseous products wherein the liquid products predominate and wherein reactor tubing and valve plugging due to carbonate salt formation is reduced by reacting crushed low-rank coal containing about 12 to 30 by weight of water in a solvent at a

Coal Liquefaction is the process of converting coal to liquid fuels Coal Liquefaction Definition The process of coal liquefaction creates synthetic liquid fuels from solid coal as substitutes for various petroleum products There are two types of liquefaction - direct and indirect Williams R H Larson E D December 2003 A comparison of direct and indirect liquefaction technologies for

Modeling coal conversion processes is a very complex topic The main conversion steps of pyrolysis and char consumption are characterized by numerous phenomena which have to be addressed by coal conversion models Often these models focus on one conversion step describing either coal pyrolysis or char consumption

Coal gasification any process of converting coal into gas for use in illuminating and heating The first illuminating gas was manufactured from coal in England in the late 18th century by the process of carbonization or destructive distillation heating coal in the absence of air leaving a …

This invention is directed to a process for converting coal into useful liquids solids and gases by combined processes of coal carbonization and liquefaction in which the carbonization reaction yields hydrogen suitable for the liquefaction The heavy liquid products from the liquefaction and the carbonization may be combined with the solid char to form a metallurgical coke

Processing the Coal After coal comes out of the ground it typically goes on a conveyor belt to a preparation plant that is located at the mining site The plant cleans and processes coal to remove dirt rock ash sulfur and other unwanted materials increasing the heating value of the coal Source Energy Information Administration
