ABSTRACT:
A process for the depolymerization of coal which includes contacting coal with phenol and a Bronsted acid catalyst at elevated temperatures and pressures for a period of about 5 minutes. The liquid coal extract which results from this process can be subjected to hydrogenolysis to produce a liquid hydrocarbonaceous product oil.
