ABSTRACT:
Process and apparatus for extraction of oil and hydrocarbons from crushed hydrocarbonaceous solids, such as tar sands, involving the pyrolyzing of the said solids with syn gas rich in hydrogen, and preferably syn gas obtained from the gasification of coal. Crushed hydrocarbonaceous solids are treated with hot syn gas containing hydrogen at an elevated temperature in a rotary kiln where the crushed solids are cascaded into the hot syn gas containing hydrogen for sufficient time to strip the volatile liquids and gases found in the said solids, removing the vaporized liquids, enriched syn gas and spent crushed solids from the kiln, fractionating the vaporized liquids and enriched syn gas into desired fractions, and utilizing the enriched syn gas in the preparation of desired by-products. The apparatus includes an improved rotary kiln which speeds the pyrolysis of the crushed solids.
