Abstract
As for brown coal liquefaction, reports are made on data on two-stage liquefaction BCL method PDU solvent deashing of CLB (coal liquid bottom), effects of liquefaction catalyst, and hydrocracking behavior of second stage hydrogenation raw material, DAO (deashed oil). Concerning bituminous coal liquefaction, as NEDOL process BSU and PSU data, described are catalyst, high concentration coal slurry, experiment on Wandoan coal liquefaction, and formation of solids in the reaction tower. As to liquefaction characteristics and reaction mechanism, reported are extensive studies on coal structures, experiments by use of model materials, functions of catalyst and solvent, and reaction condition. Decomposition of coal, liquefaction residue and char, characteristic of gasification, and characteristics of catalyst and desulfurization are studied. Pretreatment such as solvent swelling and decomposition extraction, and their effects on liquefaction are also studied. Coprocessing is reported as an engineering problem. In addition, upgrading of coal-derived liquid is studied.
