An energy integrated process for the production of a synthetic crude oil product from heavier oils and coal in which coal is pyrolyzed and a combined feedstock of coal, coal volatiles and a heavy oil product is co-processed to produce a synergistic yield of light crude oil compatible with the refining capabilities of existing conventional refineries.

A process for the production of a synthetic crude oil by co-processing non-coal heavy oil and coal comprising the steps of: (1) producing coal volatiles and a hydrocarbon residual by thermal pyrolysis of a first allotment of crushed coal using temperatures that avoid thermal degradation of the coal

A process for the production of a synthetic crude oil by co-processing non-coal heavy oil and coal comprising the steps of: (1) producing coal volatiles and a hydrocarbon residual by thermal pyrolysis of a first allotment of crushed coal using temperatures that avoid thermal degradation of the coal volatiles; (2) gasifying said hydrocarbon residual to produce a synthesis gas in first gasifiers moderated by one or more of the group consisting of air, oxygen or oxygen enriched air; (3) utilizing the sensible heat in said synthesis gas to effect the said thermal pyrolysis of said crushed coal and produce said coal volatilies; (4) condensing the condensible coal volatiles from the synthesis gas and mixing the coal volatiles with a second allotment of crushed coal and a non-coal heavy oil to produce an upgrader feedstock; (5) upgrading said feedstock by hydrogen addition comprising hydrogenation and catalytic hydrocracking to produce an upgrader lighter crude oil, an upgrading residual, and an upgrading off gas.
