Abstract: Process and apparatus for extraction of oil and hydrocarbons from crushed hydrocarbonaceous solids (101), such as oil shale, involving the pyrolyzing of the crushed solids (101) with liquid hydrocarbon (104) and hot gas such as syn gas (103) rich in hydrogen, carbon dioxide and carbon monoxide or a solid hydrocarbon such as gilsonite. Crushed hydrocarbonaceous solids are treated with a hydrocarbon and hot gas in a rotary kiln (105) where the crushed solids are cascaded into the hot gas for sufficient time to strip the volatile liquids and gases found in the solids, removing the vaporized liquids, enriched hot gas and spent crushed solids from the kiln, fractionating the vaporized liquids (106) and enriched syn gas into the desired fractions. Use of hot syn gas is particularly suited for use in conjunction with combined-cycle electricity generation (110) and in the preparation of various by-products.
