Abstract
Publisher Summary This chapter describes the coupgrading reactions of the mixture of coal liquefaction residue (CLR) and coal liquid fraction and the synergistic effects for hydrogenolysis. CLR produced abundantly in the process of hydrogenolysis reaction of coal are constituted of the heavy materials of aromatic compounds with poor reactivities. Minerals in coal are concentrated in CLR. The dichloromethane soluble in CLR acts as a good hydrogen-donor. The studies that utilize CLR as the useful carbon resources are widely practiced. The primary hydrogenolysis products yielded simultaneously with CLR contain significant amounts of basic fraction, and the secondary hydrogenolysis reactions for purposes of the effective denitrogenation of basic fraction are also necessitated.
