ABSTRACT:
Hydrocarbon oils and gases of high Btu content are produced from coal in a pressurized closed cyclic system through which hydrogen is recycled. Coal, oxygen and steam are fed into the pressurized system and oil and high Btu gas are removed as products. The system includes a coal gasification zone and coal and tar hydrogenation zones which receive hydrogen-containing gases from the coal gasification zone along with recycle hydrogen. The product oil is separated from the combined effluent of the hydrogenation zones and the resulting gases are then purified and separated into product hydrocarbon gases and recycle hydrogen without substantial reduction in system pressure.
