ABSTRACT:
Crushed coal is mixed with hot hydrogen, at 500.degree. to 1,500.degree.C. and 600 to 3,000 psig., in a reactor, and then, after a short reaction time, rapidly quenched. The total heat-up, reaction, and quench time is less than 2 seconds. This short residence time results in less gas production and less polymerization of the liquid components.
