    摘要: The present disclosure provides a method for separating soluble organic matter in petroleum coke, including: drying the petroleum coke to obtain pretreated petroleum coke; extracting the pretreated petroleum coke sequentially with petroleum ether, carbon disulfide, ethanol, acetone-carbon disulfide mixture and tetrahydrofuran to obtain an extract and the treated petroleum coke, wherein the extract includes soluble organic matter. The method provided by the present disclosure employs extractants with different polarities, i.e., petroleum ether, carbon disulfide, ethanol, acetone-carbon disulfide mixture and tetrahydrofuran, to extract petroleum coke sequentially, so as to detect the composition of the soluble organic matter in petroleum coke at the molecular level, realizing the separation of soluble organic matter in petroleum coke at the macro molecular level, as well as the determination of molecular structure of soluble organic matter in petroleum coke by modern detection processes.

    摘要: A method and apparatus for extracting bitumen and other hydrocarbons from oil-wetted tar sands and converting it to useful petroleum products, the method comprising first mixing the tar sands material with a condensate consisting oil material and agitating the resulting slurry. After agitating the slurry it is passed through a dual-phase centrifuge and the bitumen and heavy end hydrocarbons are removed, while the light end hydrocarbons remain in the centrifuge cake. The centrifuge cake is heated as it passes through an indirect fired rotary thermal desorber and the hydrocarbon material evaporates are cooled in a quench tank to be collected in the quench supply and recovery tank. The process can also be applied to materials which have become contaminated by hydrocarbons, to extract and remove the hydrocarbons. Another embodiment of the process involves using the indirect fired rotary thermal desorber to treat either tar sands material or a centrifuge cake and quenching the hydrocarbon material evaporates within the quench tank to be collected in the quench supply and recovery tank.

    摘要: The invention relates to continuous process for converting carbonaceous material contained in one or more feedstocks into a liquid hydrocarbon product, said feedstocks including the carbonaceous material being in a feed mixture including one or more fluids, said fluids including water and further liquid organic compounds at least partly produced by the process in a concentration of at least 1% by weight, where the process comprises converting at least part of the carbonaceous material by pressurizing the feed mixture to a pressure in the range 50-400 bar; heating the feed mixture to a temperature in the range 250-500° C., maintaining said pressurized and heated feed mixture in the desired pressure and temperature ranges in a reaction zone for a predefined time; cooling the feed mixture to a temperature in the range 25-200° C. and expanding the feed mixture to a pressure in the range of 1-70 bar, thereby causing the carbonaceous material to be converted to a liquid hydrocarbon product; at least partly expanding said converted feed mixture in a flash separation step, wherein the converted feed mixture is separated into a gas phase and a liquid phase, and wherein liquid CO2 is recovered from said gas phase, and separating from the liquid phase a fraction comprising liquid hydrocarbon product.
