Abstract: Provided is an improved hydroprocessing process allowing one to realize superior isoselectivity. The process comprises contacting a feed comprised of normal hydrocarbons under hydroprocessing conditions with a catalyst comprising delaminated SSZ-70. The delaminated SSZ-70 has been found to provide unexpected improvements in the catalysis of hydroprocessing hydrocarbons. Delaminated SSZ-70 offers a zeolite layer with a single unit cell of thickness in one dimension, allowing an elimination of mass transfer in comparison with non-delaminated SSZ-70.

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.
