摘要: Disclosed is a process for completely destroying oxygenates in a feed stream. The feed stream of oxygenates typically includes olefins and it is reacted with hydrogen over a catalyst comprising a top row of Group VIII metal and a Group VI-B metal. Olefins are essentially completely saturated and any sulfur compounds present in the feed are completely converted to hydrogen sulfide. A preferred catalyst includes 2 to 5 wt-% nickel, 5 to 15 wt-% molybdenum, at least 5.5 wt-% sulfur, less than 0.05 wt-% phosphorus and no more than 0.3 wt-% silicon. The catalyst has low acidity and therefore does not promote the cracking of desired oligomeric products. The deoxygenation process is preferably a saturation process that follows an oligomerization process in which light olefins are oligomerized to heavy olefins. The saturation catalyst preferably has lower acidity which causes minimal cracking of desired oligomeric products. However, by optimally raising the temperature of the outlet of the saturation reaction zone, excessively heavy oligomers can be cracked down to desirable heavy oligomers.

摘要: A process and apparatus are disclosed for hydrotreating a hydrocarbon feed in a hydrotreating unit and hydrocracking a second hydrocarbon stream in a hydrocracking unit. The hydrocracking unit and the hydrotreating unit may share the same recycle gas compressor. A make-up hydrogen stream may also be compressed in the recycle gas compressor. The second hydrocarbon stream may be a diesel stream from the hydrotreating unit. The diesel stream may be a diesel and heavier stream from a bottom of a hydrotreating fractionation column.

摘要: A process has been developed for producing diesel boiling range fuel from renewable feedstocks such as plant oils, animal fats and oils, and greases. The process involves treating a renewable feedstock by hydrogenating and deoxygenating to provide a diesel boiling 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 treatment zone to increase the hydrogen solubility of the reaction mixture.

摘要: A process has been developed for producing diesel boiling range fuel from renewable feedstocks such as plant oils and animal oils, fats, and greases. The process involves treating a renewable feedstock by hydrogenating and deoxygenating i.e. decarboxylating, decarbonylating, and/or hydrodeoxygenating to provide a hydrocarbon fraction useful as a diesel boiling range fuel or diesel boiling range fuel blending component. If desired, the hydrocarbon fraction can be isomerized to improve cold flow properties. A portion of the hydrogenated and deoxygenated feedstock is selectively separated and then recycled to the treatment zone to increase the hydrogen solubility of the reaction mixture.

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.
