Garg, D; Sunder, S

This patent describes a process for catalytic solvent refining of coal at an elevated temperature and pressure in the presence of hydrogen and a hydrocarbon solvent to produce liquid hydrocarbons and normally solid solvent-refined coal. The improvement described here comprises using as catalyst a mixture of: (a) from 0.01 to about 5% by weight of a mono- or polycyclic, substituted or unsubstituted 1.4- or 1.2-quinone with respect to coal feed and (b) from 0.01 to about 5% by weight of an ammonium, alkali metal, or alkaline earth metal compound selected from an oxide, hydroxide or salt of a weak acid, with respect to coal feed.
