This paper reviewed the characteristics and gasification behavior of residues from direct coal liquefaction and demonstrated the probability and rationality of residue gasification to produce hydrogen. An integrated coal hydrogenation process was discussed. This process is a combination of coal liquefaction process and residue gasification process, which lays emphasis on balance between liquefaction and gasification. It may result in reduced overall liquefaction cost and enhance the overall feasibility of the direct coal liquefaction itself.
