<p>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 syn gas (103) rich in hydrogen and carbon dioxide. Crushed hydrocarbonaceous solids are treated with liquid hydrocarbon and hot syn gas at an elevated temperature in a rotary kiln (105) where the crushed solids are cascaded into the hot syn gas for sufficient time to strip the volatile liquids and gases found in the solids, removing the vaporized liquids, enriched syn gas and spent crushed solids from the kiln, fractionating the vaporized liquids (106) and enriched syn gas into the desired fractions. The enriched syn gas is particularly suited for use in combined-cycle electricity generation (110) and in the preparation of various by-products. The process efficiently recycles heat and energy to reduce harmful atmospheric emissions and reliance on external energy sources.</p> |
