[0074] The operation of the process of the invention is illustrated by the following example showing the use of hot syn gas obtained from the gasification of eastern coal and crude oil for the pyrolysis of Green River oil shale.
[0075] For the hot syn gas production step, 5,000 lbs. of eastern coal was dried to between 2% and 8% moisture and crushed to particle size of about 0.75 inch. The crushed coal was conveyed into a feed bin where it was continuously discharged into a mixed nozzle where it was entrained in oxygen and low-pressure steam. Moderate temperature and high burner velocity prevented the reaction of coal and oxygen before entry into the gasification zone. The oxygen, steam and coal reacted in the gasifier at a temperature of 3330° F. The carbon and volatile matter of the coal was gasified to produce a hot syn gas, and the coal ash converted into a molten slag. About 50-70% of this slag was dropped into a water quench tank and was carried from the tank to the disposal s...

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. The process efficiently recycles heat and energy to reduce harmful atmospheric emissions and reliance on external energy sources.
Description
RELATED APPLICATIONS [0001] This application is a continuation-in-part of U.S. application Ser. No. 11 / 035,383, filed Jan. 12, 2005, which is a continuation-in-part of PCT Application No. PCT / US2003 / 021926, filed Jul. 14, 2003, which designated the United States and claims priority to U.S. application Ser. No. 10 / 194,993, filed Jul. 12, 2002, now issued as U.S. Pat. No. 6,709,573, each of which are incorporated herein by reference in their entireties.FIELD OF THE INVENTION [0002] This invention is related to the recovery of hydrocarbons from solid carbonaceous materials, and more specifically to an improved process using hot gas and liquid hydrocarbon in a generally horizontal rotary kiln. BACKGROUND OF THE INVENTION [0003] Worldwide demand for hydrocarbons and related petrochemicals and fertilizers is increasing at a rapid annual rate. Crude petroleum and natural gas are basic in satisfying these demands while at the same time many industries have experienced shortages despite the ...
