Method for coal liquefaction
Abstract
A process is disclosed for coal liquefaction in which minute particles of coal in intimate contact with a hydrogenation catalyst and hydrogen arc reacted for a very short time at a temperature in excess of 400 C at a pressure of at least 1500 psi to yield over 50% liquids with a liquid to gaseous hydrocarbon ratio in excess of 8:1. 1 figures.
