    摘要： Values are recovered from a hydrocarbon-containing vapor by contacting the vapor with quench liquid consisting essentially of hydrocarbons to form a condensate and a vapor residue, the condensate and quench fluid forming a combined liquid stream. The combined liquid stream is mixed with a viscosity-lowering liquid to form a mixed liquid having a viscosity lower than the viscosity of the combined liquid stream to permit easy handling of the combined liquid stream. The quench liquid is a cooled portion of the mixed liquid. Viscosity-lowering liquid is separated from a portion of the mixed liquid and cycled to form additional mixed liquid.

    摘要： An integrated upgrading process is disclosed which can be used to lower the specific gravity, viscosity and boiling range of heavy, viscous hydrocarbonaceous oil by means of fractionally distilling the oil, treating its residuum with a hydrogen donor material under hydrocracking conditions, fractionally distilling the effluent from the hydrocracking zone and rehydrogenating that portion boiling from about 180.degree. C. to 350.degree. C. for recycling to the hydrocracking zone. The liquid portion of the oil not recycled can be recombined into a reconstituted crude suitable for transporting by normal crude pipelines.

    摘要： A process is provided for the desulfurization of residual oil by(a) separating the residual oil into a first and a second fraction;(b) reacting the first fraction with hydrogen over a hydrodesulfurization catalyst in a first reaction zone at hydrodesulfurization conditions such that a liquid effluent of lower sulfur content than the residual oil is obtained;(c) combining the hydrodesulfurization liquid effluent with the second residual oil fraction; and(d) reacting the resultant mixture over a hydrogenation/dehydrogenation catalyst in a second reaction zone at hydrogen transfer conditions.This process provides for desulfurization of residual oils at lower hydrogen consumptions than conventional processes.
