Library. Direct Liquefaction Processes. Reason for Discussion of Direct Liquefaction of Coal in Gasifipedia. As the following discussion of Direct Coal Liquefaction (DCL) explains, the fundamental process approach of DCL does not involve gasification at all. Therefore it would seem to be entirely out of scope of Gasifipedia.

In industrial chemistry, coal gasification is the process of producing syngas—a mixture consisting primarily of carbon monoxide (CO), hydrogen (H 2), carbon dioxide (CO 2), methane (CH 4), and water vapour (H 2 O)—from coal and water, air and/or oxygen.. Historically, coal was gasified to produce coal gas, also known as "town gas".Coal gas is combustible and was used for heating and ...

Re: Coal Liquefication how does it work? just route al HO through a singl tank first and loop back into the refinieries. Then add a second output qith a pump right behind it into the fracking columns. one ciruit wire connects the pump to the tank and is set to "enable > 10000 HO". This is all it takes.

coal liquefaction, any process of turning coal into liquid products resembling crude oil. The two procedures that have been most extensively evaluated are carbonization—heating coal in the absence of air—and hydrogenation—causing coal to react with hydrogen at high pressures, usually in the presence of a catalyst.
