A process for the simultaneous catalytic hydrogenation of coal and a petroleum-derived slurrying oil to produce predominantly hydrocarbon liquid products, employing an ebullated bed catalytic hydrogenation reaction step. In the process, particulate coal is admixed with the slurrying oil comprising from about 5% to 100% by weight catalytic cracker aromatic decant oil boiling in the range of about 300-1000 F. The coal-oil slurry is reacted with hydrogen in an ebullated bed of particulate hydrogenation catalyst to effect substantial conversion of the coal and the slurrying oil component to produce a range of liquid products including an increased percentage of C4-650.degree.F boiling range fraction product. In an alternate embodiment of the process, the oil feed includes an increased percentage of petroleum-derived decant oil and heavy coal-derived recycled oil from the product liquids. If desired, some of the C4-400.degree.F naphtha product fraction can be returned to the petroleum refinery catalytic cracker to produce additional gasoline product. |
