摘要： A process for increasing the production of Bright Stock oil in a lube oil process scheme. Aromatic extract oil, after being separated from the extraction solvent, is recycled back to the deasphalter unit and combined with a vacuum residuum in 10-20 LV %, based on the total deasphalter feed, prior to deasphalting. After deasphalting and aromatics extraction the absolute yield of raffinate is increased.

摘要： Slack waxes and synthetic wax are isomerized and processed into high viscosity index and very low pour point lube base stock oils and blending stocks by the process comprising the steps of hydrotreating the wax, if necessary, to remove heteroatom and polynuclear aromatic compounds and/or deoiling the wax, if necessary, to an oil content between about 5-20% oil, isomerizing the wax over a Group VI-Group VIII on halogenated refractory metal oxide support catalyst, said isomerization being conducted to a level of conversion such that .about.40% and less unconverted wax remains in the 330.degree. C..sup.+, preferably the 370.degree. C..sup.+ fraction sent to the dewaxer. The total isomerate from the isomerization unit is fractionated into a lube oil fraction boiling at 330.degree. C..sup.+, preferably 370.degree.p9 C..sup.+. This oil fraction is solvent dewaxed preferably using MEK/MIBK at 20/80 ratio and unconverted wax is recycled to the isomerization unit. Operating in this manner permits one to obtain isomerate oil of very high VI (in excess of 130) possessing low pours (-21.degree. C., preferably -24.degree. C., most preferably -27.degree. C.).

摘要： A method for increasing the production of deasphalted oil is described. The method comprises passing a hydrocarbon feedstock into a first distillation zone wherein the feedstock is separated into a first distillate and a first residuum. First residuum is passed to a second distillation zone wherein the fraction is separated into a second distillate and a second residuum. Second distillate and residuum are passed to a deasphalting zone and contacted with a solvent to produce a deasphalted oil. This method may produce increased quantities of acceptable quality deasphalted oil where the deasphalting zone is rate-limiting.
