The present trends of the research and development in the solvolysis liquefaction of coal are reviewed.It is stressed that the solvolysis liquefaction process is a hybrid process containing the lowtemperature thermal cracking of petroleum heavy residues and the liquefaction of coal by extractive chemical disintegration.For the more development of the solvolysis liquefaction, the importance of vehicles design is considered.And also the short contact time solvolysis and qualifying process of coal liquefaction is proposed.
