Abstract:
1. A process for conversion of heavy oils to produce lower boiling hydrocarbon products comprising: a) dispersing finely divided coal and catalyst in a heavy oil feedstock to obtain a dispersed mixture, b) heating and passing the dispersed mixture together with hydrogen to a first reaction zone comprising one or more thermo-catalytic reactors, c) converting a portion of the coal into coal liquids in the first reaction zone, d) mixing heavy oils in the heavy oil feedstock, the coal liquids, and the dispersed catalyst in the first reaction zone to convert the heavy oils to an effluent comprising hydrocarbons boiling below 1000.degree. F., e) passing at least a portion of the effluent comprising hydrocarbons boiling below 1000.degree. F. reduced in temperature to a second reaction zone comprising one or more catalytic-hydrotreating reactors and having a supported hydrotreating catalyst, and f) recovering a product of the second reaction zone,
