    摘要: A method is disclosed for recovering liquids and gases by a rapid hydropyrolysis of carbonaceous solids which comprises subjecting the carbonaceous material in a stream of carrier gas to a first pressure and a first temperature below the decomposition temperature of the carbonaceous material; reducing substantially in a single step the pressure on the stream of carbonaceous material from the first pressure to a second pressure, the ratio of the first pressure to the second pressure being at least 1.6, thereby accelerating the carrier gas in the stream of carbonaceous material; permitting the accelerated stream of carbonaceous material to expand as a free jet and mixing hot gas with the accelerated and expanded stream of carbonaceous material to raise the temperature of the carbonaceous material by heat exchange with the hot gas, to a second temperature of at least the aforesaid decomposition temperature, thereby initiating decomposition of the carbonaceous material; and reducing the temperature of the reaction mixture to below said decomposition temperature, with the total time for heating the carbonaceous material from the first temperature to the second temperature, decomposing the carbonaceous material and cooling the reaction mixture to below said decomposition temperature being from about 1 millisecond to about 10 seconds.

    摘要: A method for stabilizing oil is provided. An oil fraction having hydrocarbons with an initial boiling point of about 200.degree. F. to about 1050.degree. F. is hydrotreated to reduce the nitrogen content of the oil fraction to be stabilized. Subsequently, condensed aromatic compounds are selectively extracted from the hydrotreated oil fraction to yield a stable oil fraction.

    摘要: A process is provided to produce and stabilize shale oil. In the process, raw oil shale is retorted with heat carrier material to liberate an effluent product stream comprising hydrocarbons and entrained particulates of oil shale dust. In order to minimize polymerization of the product stream and enhance agglomeration of the shale dust, the product stream is stabilized with a hydrogen donor quench upon exiting the retort. The quenched stream is subsequently dedusted and upgraded.
