METHOD FOR COAL LIQUEFACTION

摘要

A process is disclosed for coal liquefaction in which minute particles of coal in intimate contact with a hydrogenation catalyst and hydrogen are reacted for a very short time at a temperature in excess of 400 DEG C at a pressure of at least 1,700 kilonewtons per square meter (250 psi) to yield over 50 % liquids with a liquid to gaseous hydrocarbon ratio in excess of 8:1.
