Abstract
Coal liquefaction technology was established in Germany in 1920s. Coal liquefaction refers to the process in which coal is converted into liquid fuels such as gasoline and diesel oil under certain conditions. Coal liquefaction is usually classified into direct coal liquefaction (DCL) and indirect coal liquefaction (ICL). Various technologies for coal liquefaction, conducted between 1970s and 2000s, resulted in the development and optimization of a communication ready technology for the production of petroleum substitutes as refinery feedstocks. The purpose of this paper is to review the research, development and demonstration of coal liquefaction. In these respects, various DCL and ICL processes under development were illustrated and compared. Also, the status and perspective of coal liquefaction projects in the world were viewed. Considering the scale, and technical difficulties of domestic coal liquefaction, the project has be leaded by the government.
