Abstract: A process to make an alkylate base oil having a viscosity index greater than or equal to 90, comprising: a. converting an at least one dimeric ketone to an at least one alcohol; b. dehydrating the at least one alcohol to make one or more corresponding olefins; and c. alkylating at least one isoalkane with the one or more corresponding olefins to form the alkylate base oil.

Abstract: This invention discloses a process for making high viscosity index lubricating base oils having a viscosity index of at least 110 by co-feeding a ketone or a beta-keto-ester feedstock with a lubricant oil feedstock directly to a hydrocracking unit to produce a hydrocracked stream. Then at least a portion of the hydrocracked stream is treated under hydroisomerization conditions to produce a high viscosity index lubricating base oil. The process may involve bypassing a hydrotreating or hydrofinishing step, which may result in improved efficiency and economics in producing high viscosity index lubricating base oils.

Abstract: Processes for upgrading Fischer-Tropsch condensate olefins by alkylation of hydrocrackate involves providing an olefin enriched condensate stream and further providing a Fischer-Tropsch derived hydrocarbon stream comprising wax, hydrocracking the latter Fischer-Tropsch hydrocarbon stream to provide a distillate enriched hydrocracked product comprising isoparaffins, and alkylating the olefins with the isoparaffins in an alkylation zone to provide an alkylate product. The alkylate product is fed to a distillation unit together with the hydrocracked product, while a naphtha containing fraction from the distillation unit is fed to the alkylation zone together with the olefin enriched hydrocarbon stream.
