Linear alkylbenzenes from natural oils and methods of producing

摘要

The production of linear alkylbenzene from a natural oil is 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.

主权项

1. A method for generating an alkylbenzene product from a natural oil comprising:
deoxygenating feedstock comprising natural oil having less than about 3 wt. ppm of nitrogen contained in nitrogen containing compounds to form a stream comprising 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 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.
