Linear alkylbenzenes from natural oils and methods of producing

摘要

A linear alkyl benzene product and production of linear alkylbenzene from a natural oil are provided. A method comprises the step of deoxygenating the natural oils to form a stream comprising paraffins. The paraffins are dehydrogenated to provide mono-olefins. Then, benzene is alkylated with the mono-olefins under alkylation conditions to provide an alkylation effluent comprising alkylbenzenes and benzene. Thereafter, the alkylbenzenes are isolated to provide the alkylbenzene product.

1. A method for generating an alkylbenzene product from a natural oil comprising:
deoxygenating, in a deoxygenation zone, feedstock comprising natural oil to form a stream comprising paraffins wherein the temperature of the deoxygenation zone is maintained below the effective temperature for isomerization of the paraffins; wherein the deoxygenating utilizes a catalyst comprising a first component selected from the group consisting of Ni—Mo—, Ni—Mo—P, Ni—Co—Mo, and Co—Mo and a second component selected from the group consisting of aluminas, titania, zirconia, and mixtures thereof; dehydrogenating at least a portion of the paraffins to provide mono-olefins; alkylating benzene with the mono-olefins under alkylation conditions to provide an alkylation effluent comprising alkylbenzenes and benzene; separating the alkylbenzenes to provide the alkylbenzene product comprising alkylbenzenes having an alkyl group of about n carbon atoms where n is from about 12 to about 13 and wherein the alkyl group is a linear alkyl group for at least 80 mass % of the alkylbenzenes having an alkyl group of about n carbon atoms.
