Embodiments of methods for production of linear alkylbenzene and optionally biofuel from natural oil are provided. Natural oils are deoxygenated to form a stream comprising paraffins. A first portion of 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. Optionally, a second portion of the paraffins may be processed to form biofuel.
