摘要： A method to selectively remove metal compounds and sulfur from a petroleum feedstock is provided. The method comprising the steps of feeding a pre-heated water stream and a pre-heated petroleum feedstock to a mixing zone, mixing the pre-heated water stream and the pre-heated petroleum feedstock to form a mixed stream, introducing the mixed stream to a first supercritical water reactor to produce an upgraded stream, combining the upgraded stream and a make-up water stream in a make-up mixing zone to produce a diluted stream, wherein the make-up water stream increases the ratio of water to oil in the diluted stream as compared to the upgraded stream, and introducing the diluted stream to a second supercritical water reactor to produce a product effluent stream. The method can include mixing a carbon with the make-up water stream.

摘要： Methods are provided for dewaxing a distillate fuel boiling range feed to improve one or more cold flow properties of the distillate fuel feed, such as cloud point, with reduced consumption of hydrogen during the dewaxing process. The reduced hydrogen consumption is achieved by using a dewaxing catalyst with a reduced content of hydrogenation metals, such as a content of Pt or Pd of from about 0.03 wt % to about 0.35 wt %. A distillate fuel feed can be dewaxed to achieve a desired cloud point differential using a reduced metals content dewaxing catalyst under the same or similar conditions to those required for a dewaxing catalyst with higher metals content.

摘要： A multi-stage hydrotreating process obtains ultra-low sulfur diesel boiling range hydrocarbon having less than 10 ppm sulfur with elimination of external hot high pressure separator and avoids the formation of recombinant mercaptans by removing excess hydrogen sulfide formed during hydroprocessing reaction. The process includes mixing a diesel boiling range hydrocarbon feedstock with hydrogen and sending to the first predominantly liquid phase hydroprocessing reaction stage. Effluent from the first hydroprocessing reaction stage is sent to first separator zone of open and empty space in the upper part of the second hydroprocessing reaction stage to flash off the dissolved reaction products hydrogen sulfide and ammonia. Liquid part of the effluent of first hydroprocessing reaction stage is passed to the second predominantly liquid phase hydroprocessing reaction stage. The process is repeated until the liquid product sulfur level of less than 10 ppm is attained and the liquid product is sent to further processing.

摘要： A method for refining used motor oil using two or more hydrotreating reactors arranged in series. The used motor oil may be vacuum distilled to produce an unrefined gasoil. The unrefined gasoil may then be hydrotreated in a first hydrotreating reactor with hydrogen operated at a temperature ranging from approximately 245° C. to approximately 260° C. to produce a hydrotreated gasoil. The hydrogen may comprise a mixture of fresh hydrogen and recycled hydrogen recovered from the last of the two or more hydrotreating reactors. The hydrotreated gasoil may then be hydrotreated in one or more additional hydrotreating reactors operated at temperatures ranging from approximately 260° C. to approximately 330° C. to produce a refined gasoil. The first hydrotreating reactor may remove a substantial portion of metallic impurities from the unrefined impurities, while the one or more additional hydrotreating reactors remove a substantial portion of heteroatom impurities from the unrefined gasoil.

摘要： The invention relates to a method for revamping a conventional refinery of mineral oils into a biorefinery, characterized by a production scheme which allows the treatment of raw materials of a biological origin (vegetable oils, animal fats, exhausted cooking oils) for the production of biofuels, prevalently high-quality biodiesel. This method allows the re-use of existing plants, allowing, in particular, the revamping of a refinery containing a system comprising two hydrodesulfurization units, U1 and U2, into a biorefinery containing a production unit of hydrocarbon fractions from mixtures of a biological origin containing fatty acid esters by means of their hydrodeoxygenation and isomerization, wherein each of the hydrodesulfurization units U1 and U2 comprises: a hydrodesulfurization reactor, (A1) for the unit U1 and (A2) for the unit U2, wherein said reactor contains a hydrodesulfurization catalyst; one or more heat exchangers between the feedstock and effluent of the reactor; a heating system of the feedstock upstream of the reactor; an acid gas treatment unit downstream of the reactor, containing an absorbent (B) for H2S, said unit being called T1 in the unit U1 and T2 in the unit U2, and wherein said method comprises: installing a line L between the units U1 and U2 which connects them in series; installing a recycling line of the product for the unit U1 and possibly for the unit U2, substituting the hydrodesulfurization catalyst in the reactor A1 with a hydrodeoxygenation catalyst; substituting the hydrodesulfurization catalyst in the reactor A2 with an isomerization catalyst; installing a y-pass line X of the acid gas treatment unit T2 of the unit U2; substituting the absorbent (B) in the acid gas treatment unit T1 with a specific absorbent for C02 and H2S. The operative configuration obtained with the method, object of the present invention, also leads to a substantial reduction in emissions of pollutants into the atmosphere, with respect to the original operative mode. The invention also relates to the transformation unit of mixtures of a biological origin obtained with said conversion method and particularly hydrodeoxygenation and isomerization processes.
