    Abstract: Stable catalyst carrier impregnating solutions can be prepared using a component of a Group VIB metal, e.g., molybdenum, at high concentration, a component of a Group VIII metal, e.g., nickel, at low concentration, and a phosphorous component, e.g., phosphoric acid, at low concentration, provided that the Group VIII metal is in a substantially water-insoluble form and a particular sequence of addition of the components is followed, even when a substantially water-insoluble form of the Group VIB component is used. The resulting stabilized impregnating solution can be supplemented with additional Group VIII metal in water-soluble form to achieve increased levels of such metal in the final catalyst. Furthermore, uncalcined catalyst carriers impregnated with the stable solution and subsequently shaped, dried and calcined, have unexpectedly improved performance when used in the hydroprocessing of heavy hydrocarbon feedstocks.

    Abstract: Fluid catalytic cracking (FCC) processes are described, in which hydroprocessed hydrocarbon streams or other hydrocarbon feed streams having a low coking tendency are subjected to direct heat exchange with the FCC reactor effluent, for example in the FCC main column. The processes operate with sufficient severity such that little or no net FCC main column bottoms liquid (e.g., with a 343° C. (650° F.) distillation cut point) is generated. Regeneration temperatures with the representative low coking tendency feeds are beneficially increased by using an oxygen-enriched regeneration gas stream.

    Abstract: A new residuum full hydroconversion slurry reactor system has been developed that allows the catalyst, unconverted oil and converted oil to circulate in a continuous mixture throughout an entire reactor with no confinement of the mixture. The mixture is partially separated in between the reactors to remove only the converted oil while permitting the unconverted oil and the slurry catalyst to continue on into the next sequential reactor where a portion of the unconverted oil is converted to lower boiling point hydrocarbons, once again creating a mixture of unconverted oil, converted oil, and slurry catalyst. Further hydroprocessing may occur in additional reactors, fully converting the oil. The oil may alternately be partially converted, leaving a highly concentrated catalyst in unconverted oil which can be recycled directly to the first reactor. Fully converted oil is subsequently hydrofinished for the nearly complete removal of hetoroatoms such as sulfur and nitrogen.

    Abstract: An apparatus for removing sulfur from a hydrocarbon feed includes a cell having two compartments and a membrane separating the compartments, wherein one compartment is communicated with a hydrogen source and the other compartment is communicated with the hydrocarbon feed to be treated, wherein the membrane comprises a palladium membrane which is modified to have an additional amount of a mix of palladium and other metals (Ni, Ag, Co and Au) between about 4.62*10?3 and 1.62*10?2 g/cm2; and a power source connected across the hydrogen source compartment to generate a current across same, whereby atomic hydrogen is formed from the hydrogen source at a surface of the membrane and diffuses across the membrane to react with the hydrocarbon feed. A process using this apparatus is also provided.

  • Patent number: 7651606
    Abstract: The invention concerns a process for the hydrodesulphurization of gasoline cuts for the production of gasolines with a low sulphur and mercaptans content. Said process comprises at least two hydrodesulphurization steps, HDS1 and HDS2, operated in parallel on two distinct cuts of the gasoline constituting the feed. The flow rate of hydrogen in the hydrodesulphurization step HDS2 is such that the ratio between the flow rate of hydrogen and the flow rate of feed to be treated is less than 80% of the ratio of the flow rates used to desulphurize in the hydrodesulphurization step HDS1.

  • Patent number: 7651604
    Abstract: Two-stage low pressure catalytic hydrotreatment of heavy petroleum hydrocarbons having a high content of contaminants (metals and asphaltenes), is conducted under operating conditions with low-pressure, in a fixed bed or ebullated bed reactor to limit the formation of sediments and sludge in the product and obtain a hydrotreated hydrocarbon of improved properties, with levels of contaminants, API gravity and distillates within the ranges commonly reported in the feedstocks typical to refining schemes. A hydrotreatment catalyst, whose principal effect is the hydrodemetallization and the hydrocracking of asphaltenes of the heavy hydrocarbons of petroleum is used in the first stage, and the second reaction stage employs a hydrotreatment catalyst for a deeper effect of hydrodesulfurization of the heavy petroleum hydrocarbon whose content of total sulfur is reduced to a level required for its treatment in the conventional refining process or for its sale as a hydrocarbon of petroleum with improved properties.

  • Patent number: 7648541
    Abstract: A method of removing sulfur from a fuel supply stream for a fuel cell (1), which method comprises: (a) hydrogenating the fuel supply stream (1) by contacting it with a hydrogenation catalyst in the presence of hydrogen to convert sulfur-containing compounds in the fuel supply stream (1) into hydrogen sulfide; (b) removing the hydrogen sulfide to produce a desulfurised fuel stream; and (c) pre-reforming the desulfurised fuel stream to produce a fuel cell feed stream, wherein a portion of the fuel cell feed stream is processed to increase its hydrogen content to produce a hydrogen-enriched fuel stream which is used in step (a) as a source of hydrogen to hydrogenate the fuel supply stream (1).

  • Publication number: 20090321320
    Abstract: This invention relates to a catalyst and method for hydrodesulfurizing naphtha. More particularly, a Co/Mo metal hydrogenation component is loaded on a high temperature alumina support in the presence of a dispersion aid to produce a catalyst that is then used for hydrodesulrurizing naphtha. The high temperature alumina support has a defined surface area that minimizes olefin saturation.

  • Publication number: 20090308792
    Abstract: Oil soluble catalysts are used in a process to hydrodesulfurize petroleum feedstock having a high concentration of sulfur-containing compounds and convert the feedstock to a higher value product. The catalyst complex includes at least one attractor species and at least one catalytic metal that are bonded to a plurality of organic ligands that make the catalyst complex oil-soluble. The attractor species selectively attracts the catalyst to sulfur sites in sulfur-containing compounds in the feedstock where the catalytic metal can catalyze the removal of sulfur. Because the attractor species selectively attracts the catalysts to sulfur sites, non-productive, hydrogen consuming side reactions are reduced and greater rates of hydrodesulfurization are achieved while consuming less hydrogen per unit sulfur removed.

    Abstract: A process is provided to produce high cetane quality and low or preferably ultra low sulfur diesel and a fluid catalytic cracker (FCC) quality feedstock from a processing unit including at least a hydrotreating zone and a hydrocracking zone. In one aspect, the processing unit includes reactor severity requirements in both the hydrotreating zone and the hydrocracking zone effective to produce the FCC feed quality and the diesel sulfur quality to permit a high quality hydrocracked product to be formed at lower pressures and conversion rates without overtreating the FCC quality feedstock stream. In another aspect, a portion of the hydrotreated effluent is selected for conversion in the hydrocracking and the remaining portion of the hydrotreated effluent is directed to subsequent processing, such as fluid catalytic cracking.

  • Patent number: 7588680
    Abstract: In some embodiments, the invention is a method of removing sulfur from a hydrocarbon feed using the steps of dissolving metallic sodium in a first solvent, combining the sodium/first solvent solution with a sulfur-free alkane or cycloalkane second solvent, vaporizing the first solvent from sodium/first solvent/second solvent combination to transfer the dissolved metallic sodium into the second solvent, and then combine the resultant liquid with a liquid hydrocarbon feed containing an organosulfur species. The resulting stream is combined with a hydrogen donor. The combination is heated and pressurized to form a liquid hydrocarbon product containing sodium sulfide. The liquid hydrocarbon product containing sodium sulfide is then cooled, and the sodium sulfide is extracted.
