Abstract
A method of processing hydrocarbon substances including coal, heavy crude oil, and bitumen by hydrogenating the hydrocarbon substance with a gas containing from 20%-100% hydrogen at a pressure in the range of from 50 bar to 700 bar and at a temperature in the range of from 250.degree. C. to 600.degree. C. to produce a hydrogenation residue which is treated in a secondary stripping operation using hydrogen gas at a pressure between about 1.2 bar and 150 bar to recover light hydrocarbon gases from the hydrogenation residue.
