Coal direct liquefaction was kind of technology that belong to cleaning coal technology. In the paper, the chemical reaction and the process were introduced; the requirement of raw coal for coal direct liquefaction is also mentioned. Reviewing the histoW of coal direct liquefaction in and out of China, some people put forward the conception of Integrated Coal-hydrogenation, and this should be the tendency of coal chemical industry.
