摘要： Lube base stocks and lube stock compositions, as well as a process for preparing lube base stocks and lube stock compositions, are disclosed. The lube oils preferably have a viscosity index above about 115. The process involves obtaining feed-stocks that have a 95% point below 1150° F. and feedstocks that have 95% point above 1150° F. The feedstocks that have a 95% point below 1150% are catalytically dewaxed, and the feedstocks that have 95% point above 1150% are solvent dewaxed. The resulting products can optionally be blended, and the base stocks can be combined with various additives to form lube oil compositions. Hydrotreatment can optionally be performed on the lube base stocks to remove olefins, oxygenates and other impurities. In one embodiment, one or more of the fractions are obtained from Fisher-Tropsch synthesis. One or more of the fractions can also be obtained from other sources, for example, via distillation of crude oil, provided that the fractions do not include appreciable amounts (i.e., amounts which would adversely affect the catalyst used for catalytic isodewaxing) of thiols or amines. The individual fractions can also includes combinations of feedstocks, from Fisher-Tropsch and other sources.

摘要： The invention relates to a process for reducing the cloud point of a base oil feed having a kinematic viscosity at 100° C. of greater than 10 cSt by separating the molecules inferring the high cloud point from the base oil by (a) depositing said molecules on one side of a cooled surface, (b) obtaining a base oil having a reduced cloud point and (c) melting the deposited molecules and separating the melted molecules from the surface and reusing said surface to perform step (a).

摘要： Process to prepare simultaneously two or more base oil grades and middle distillates from a mineral crude derived feed, in particular a de-asphalted oil or a vacuum distillate feed or their mixtures, by performing the following steps: (a) hydrocracking the mineral crude derived feed, thereby obtaining an effluent; (b) distillation of the effluent as obtained in step (a) into one or more middle distillates and a full range residue boiling substantially above 340° C., (c) catalytically dewaxing the full range residue by contacting the residue with a dewaxing catalyst comprising a zeolite of the MTW type and a Group VIII metal, thereby obtaining a dewaxed oil; (d) isolating by means of distillation two or more base oil grades from the dewaxed oil obtained in step (c); and (e) isolating a dewaxed gas oil from the dewaxed-oil obtained in step (c); wherein the dewaxed oil as obtained in step (c) comprises between 10 and 40 wt % of a dewaxed heavy gas oil boiling for more than 70 wt % between 370 and 400° C.
