摘要： In one aspect, a hydrodesulfurization process is provided that selectively desulfurizes a hydrocarbon stream with minimal olefin saturation and minimal recombination of sulfur into mercaptans. In another aspect, the process includes a multi-stage reaction zone including at least first and second serial hydrodesulfurization reaction zones that sequentially remove sulfur from a hydrocarbon stream. In yet another aspect, the process is particularly suited to selectively desulfurize an olefinic naphtha hydrocarbon stream, such as FCC naphtha, steam cracked naphtha, coker naphtha, or other gasoline boiling hydrocarbon streams.

摘要： A process is provided to produce an ultra low sulfur diesel with less than about 10 ppm sulfur using a two-phase or liquid-phase continuous reaction zone to convert a diesel boiling range distillate preferably obtained from a mild hydrocracking unit. In one aspect, the diesel boiling range distillate is introduced once-through to the liquid-phase continuous reaction zone over-saturated with hydrogen in an amount effective so that the liquid phase remains substantially saturated with hydrogen throughout the reaction zone as the reactions proceed.

摘要： A process is provided for producing low sulfur diesel having a high cetane number where the temperature and pressure requirements for obtaining low levels of sulfur is separated from the temperature and pressure requirements for improving cetane. In one aspect, a low pressure hydrodesulfurization zone and a high pressure aromatic saturation zone are employed to sequentially achieve the desired sulfur and cetane levels. In another aspect, the process first converts a diesel boiling range hydrocarbonaceous stream in a hydrotreating zone at conditions effective to produce a hydrotreating zone effluent having a reduced concentration of sulfur with minimal saturation of aromatics. Hydrogen is then admixed with the hydrotreating zone effluent, which is then reacted in a substantially liquid-phase continuous reaction zone substantially undiluted with other streams to effect saturation of aromatics to provide a liquid-phase continuous reaction zone effluent having an improved cetane number.

摘要： Methods of hydroprocessing hydrocarbon streams are provided that employ substantially liquid-phase hydroprocessing conditions. In one aspect, the method includes directing a hydrocarbonaceous feed stock to a first substantially liquid-phase hydroprocessing zone wherein an effluent from the first substantially liquid-phase hydroprocessing zone is directed to a second substantially liquid-phase hydroprocessing zone generally undiluted with other hydrocarbon streams. In another aspect, the method recycles a liquid portion of a liquid hydrocarbonaceous effluent from the second substantially liquid-phase hydroprocessing zone, which preferably includes an amount of hydrogen dissolved therein, to the hydrocarbonaceous feed stock so that the feed to the first substantially liquid-phase hydroprocessing zone has a relatively larger concentration of dissolved hydrogen relative to the hydrocarbonaceous feed stock.

摘要： A process has been developed for producing fuel from renewable feedstocks such as plant and animal oils and greases. The process involves treating a first portion of a renewable feedstock by hydrogenating and deoxygenating in a first reaction zone and a second portion of a renewable feedstock by hydrogenating and deoxygenating in a second reaction zone and treating the effluents in a finishing reaction zone to provide a diesel boiling point range fuel hydrocarbon product. If desired, the hydrocarbon product can be isomerized to improve cold flow properties. A portion of the hydrocarbon product is recycled to the first reaction zone to increase the hydrogen solubility of the reaction mixture.
