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. However, the following considerations require that discussion of DCL be included:

Improvement of Coal Direct Liquefaction by Steam ...

Pretreatment of coal by reaction with subcritical steam enhances its performance in direct liquefaction. Illinois No. 6 coal, first reacted with 51 atm of steam for 15 min at 340 °C, was liquefied in a coal injection autoclave to provide rapid heating. Liquefactions were carried out with raw and pretreated coal at high-severity (400 °C, 30 min) and low-severity (385 °C, 15 min) conditions ...

These processes are generally termed as coal liquefaction. Coal liquefaction may occur by two different pathways: indirect liquefaction and direct liquefaction. The indirect method converts coal to hydrogen and carbon monoxide, and syngas by reacting coal with steam at high temperatures in an oxygen-starved combustion process.
