    Abstract: A process for hydroprocessing a hydrocarbon feedstock, includes the steps of providing a hydrocarbon feed having an initial characteristic; providing a first hydrogen-containing gas; feeding the hydrocarbon feed and the first hydrogen-containing gas cocurrently to a first hydroprocessing zone so as to provide a first hydrocarbon product; providing a plurality of additional hydroprocessing zones including a final zone and an upstream zone; feeding the first hydrocarbon product cocurrently with a recycled gas to the upstream zone so as to provide an intermediate hydrocarbon product; and feeding the intermediate hydrocarbon product cocurrently with a second hydrogen-containing gas to the final zone so as to provide a final hydrocarbon product having a final characteristic which is improved as compared to the initial characteristic.

    Abstract: A method for obtaining oil products such as diesel fuel with improved quality, from a gas oil fraction containing organosulphur compounds such as dibenzenethiophenes and/or their derivatives, with initial and final boiling points generally ranging between about 170 and 480° C. The method includes at least two steps which consist in: (a) liquid-liquid extraction wherein the diesel fuel fraction is contacted with a solvent so as to obtain a gas oil-type raffinate with low content of sulphur and aromatic compounds and an extract rich in solvent and with high content of sulphur and aromatic compounds; (b) oxidation of the extract sulphur compounds so as to obtain, after separation, a heavy gas oil-type hydrocarbon effluent with low sulphur content, and a residue comprising oxidased organosulphur compounds. The invention also concerns oil products obtained by said method which can be used either for the formation of fuel for internal combustion engine with compression ignition (of the diesel type) or as fuel.

    Abstract: A hydrofining process in which a sulfur- and hydrocarbon-containing processing stream is supplied to a multi-stage hydrotreating reactor incorporating separate stages of cobalt molybdenum catalysts. Hydrogen may be supplied concurrently or counter-currently with the hydrocarbon-containing processing stream. The processing stream is passed into contact with an initial catalyst stage comprising a cobalt molybdenum desulfurization catalyst present in a minor amount of the total composite amount of catalysts within the reactor. Thereafter the processing stream is passed through a subsequent catalyst stage comprising a major amount of cobalt molybdenum hydrocracking catalyst. The effluent stream having a reduced sulfur content is then withdrawn from the hydrotreating reactor. The initial and subsequent catalyst stages are separated by an intervening sector within the reactor containing an inert particulate refractory material, specifically silica particles generally spheroidal in shape.

    Abstract: A process for concurrently fractionating and treating of a full range naphtha stream. The full boiling range naphtha stream is first subjected to simultaneous thioetherification or selective hydrogenation and splitting into a light boiling range naphtha, an intermediate boiling range naphtha and a heavy boiling range naphtha. The intermediate boiling range naphtha containing thiophene and thiophene boiling range mercaptans, dienes or mixtures may be subjected to a second thioetherification or selective hydrogenation, depending on its make-up, and then passed on to a polishing hydrodesulfurization reactor or the entire intermediate stream may be passed directly to the polishing reactor. The bottoms are subjected to concurrent hydrodesulfurization and fractional distillation and the combined overheads and bottoms are fed to the polishing reactor. The effluent from the polishing reactor may be combined with the light boiling range naphtha to produce a new full boiling range naphtha containing substantially less total sulfur than the original feed. The object being to meet higher standards for sulfur removal, by treating the components of the naphtha feed with the process that preserves the olefinic while most expediently removing the sulfur compounds.

    Abstract: A hydrotreating process is presented for both dewaxing the diesel fraction and reducing the aromatic content of kerosene fraction of a distillate boiling range feed stream. The feed stream is flashed to generate vapor and liquid phase streams. The portion which comprises most of the heavy diesel is passed into a dewaxing zone. The vapor-phase stream, preferably rich in kerosene and light diesel, is used to quench the effluent of the dewaxing zone before it is passed into a downstream aromatics hydrogenation zone. Depending on the composition of the feed to the process, a second flashing step performed in the presence of added hydrogen may be employed to produce the feed to the dewaxing zone. PNA's may be hydrogenated prior to recycling to a hydrocracking zone.
