Methods for co-production of alkylbenzene and biofuel from natural oils using hydrocracking

摘要

Embodiments of methods for the production of linear alkylbenzene and optionally biofuel from a natural oil are provided. A method comprises the step of deoxygenating the natural oils to form paraffins. A first portion of the paraffins is hydrocracked to form a first stream of normal and lightly branched paraffins in the C9 to C14 range and a second stream of isoparaffins. The first stream is 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. Optionally a second portion of the paraffins and the isoparaffins are processed to form biofuel.

1. A method for production of an alkylbenzene product from a natural oil comprising:
deoxygenating the natural oil to form paraffins; hydrocracking a first portion of the paraffins to form a first stream of normal or lightly branched paraffins in the C9 to C14 range and a second stream of isoparaffins; dehydrogenating the first stream to provide mono-olefins, di-olefins, and aromatics; selectively hydrogenating the di-olefins to form additional mono-olefins and separating and removing the aromatics from the mono-olefins before alkylating; alkylating benzene with the mono-olefins under alkylation conditions to provide an alkylation effluent comprising alkylbenzenes and benzene; isolating the alkylbenzenes to provide the alkylbenzene product.
