Abstract:
1. A method for producing a linear alkylbenzene product from a bio-renewable feedstock comprising a natural oil, the method comprising the steps of: hydrogenating, deoxygenating, isomerizing, and selectively hydrocracking the renewable feedstock in a hydrogenating-deoxygenating-isomerizing-selectively hydrocracking unit containing a composite catalyst comprising a first portion comprising a catalyst comprising nickel or nickel/molybdenum or cobalt, cobalt/molybdenum or sulfided NiMo supported on amorphous silica-alumina or platinum on amorphous silica-alumina and a second portion comprising a catalyst comprising platinum and/or palladium on a support containing on Y-zeolite bound with amorphous silica-alumina to produce a hydrocarbon mixture to produce a hydrocarbon mixture; separating the hydrocarbon mixture into a naphtha portion and a distillate portion; reforming the naphtha portion in the presence of a reforming catalyst to produce a reformate product containing benzene; separating the reformate product in a high purity aromatics extraction separation unit by using a 2,3,4,5-tetrahydrothiophene-1,1-dioxide solvent to extract benzene to produce a high purity benzene stream; separating a normal paraffins portion from the distillate portion and dehydrogenating the normal paraffins portion to produce mono-olefins; and reacting the benzene and the mono-olefins in the presence of hydrogen fluoride or an aluminum chloride catalyst, or a solid bed alkylation catalyst comprising fluoridated silica alumina or zeolites comprising one or more of FAU, MOR, UZM-8, Y, X RE exchanged Y, RE exchanged X, amorphous silica-alumina, and mixtures thereof to produce the linear alkylbenzene product.
