(204° C.) to 1500° F. (816° C.) or more. The upgraded raffinate and/or extract products can have a reduced or minimized concentration of sulfur, nitrogen, metals, or a combination thereof. The reduced or minimized concentration of sulfur, nitrogen, and/or metals can be achieved by hydrotreating a suitable feed under hydrotreatment conditions corresponding to relatively low levels of feed conversion. Optionally, the feed can also dewaxed, such as by catalytic dewaxing or by solvent dewaxing. Because excessive aromatic saturation is not desired, the pressure for hydrotreatment (and optional dewaxing) can be 500 psig (˜3.4 MPa) to 1200 psig (˜8.2 MPa).

  • Patent number: 9587184
    Abstract: Methods are provided for producing a plurality of lubricant base oil products with an increased overall yield. Prior to the final hydrocracking stage for viscosity index uplift, a feed for making a lubricant base oil is fractionated in order to form at least a feed for making a lighter lubricant base oil and a feed for making a heavier lubricant base oil. The fractionation cut points are selected to so that the feed fraction for forming a light lubricant base oil has a higher Noack volatility and a lower viscosity than the desired targets for the lighter lubricant base oil. The feed fractions are then hydroprocessed separately to achieve desired properties. After hydroprocessing, a portion of the heavier base oil is blended into the light lubricant base oil to produce a blended base oil product. This returns the volatility and the viscosity of the blended base oil to the desired specifications.

    Abstract: Embodiments of methods for making renewable diesel by deoxygenating (decarboxylating/decarbonylating/dehydrating) fatty acids to produce hydrocarbons are disclosed. Fatty acids are exposed to a catalyst selected from a) Pt and MO3 on ZrO2 (M is W, Mo, or a combination thereof), or b) Pt/Ge or Pt/Sn on carbon, and the catalyst decarboxylates at least 10% of the fatty acids. In particular embodiments, the catalyst consists essentially of 0.7 wt % Pt and 12 wt % WO3, relative to a mass of catalyst, or the catalyst consists essentially of a) 5 wt % Pt and b) 0.5 wt % Ge or 0.5 wt % Sn, relative to a mass of catalyst. Deoxygenation is performed without added hydrogen and at less than 100 psi. Disclosed embodiments of the catalysts deoxygenate at least 10% of fatty acids in a fatty acid feed, and remain capable of deoxygenating fatty acids for at least 200 minutes to more than 350 hours.

  • Patent number: 8795112
    Abstract: An oil-free chain is constructed by alternately connecting a pair of outer link plates connected using pins and a pair of inner link plates connected using oil-impregnated bushings into which the adjacent pins of the outer link plates adjacent to the inner link plates are fitted. The oil-impregnated bushings are impregnated with a lubricant having a kinematic viscosity in the range of ISO-VG grade 46 to 460, the weight % of an ingredient having the highest content among the elution ingredients obtained by the GPC method is 95 wt % or more, Mn is 800 or more and 2300 or less, and the ratio of Mw to Mn is 1.0 or more and 1.3 or less. Oil film breakage at the sliding portions of the bushings is suppressed from occurring and the oil film strength is high such that an oil-free chain has a sufficiently long abrasion elongation-resistant life.
