A multi-stage coal liquefaction process under development at Kyushu University for the past 10 years is reviewed. The process consists of five major stages of pretreatment of coal: primary hydrogen transfer liquefaction by short contact time reaction at higher temperature: hydrogenation and hydrorefining stages of reaction applied to coal-derived liquids, and preparation of liquefaction solvent, to achieve high yields of refined oil at moderate pressure through the whole process. The problems to be solved in the respective stages are also described.
