NOVELTY - Generating an alkylbenzene product from a natural oil, comprises: deoxygenating the natural oil consisting of palm kernel oil, coconut oil and/or babassu oil to form a stream comprising paraffins; 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; and separating the alkylbenzenes to provide the alkylbenzene product comprising alkylbenzenes having 12-13C alkyl group.    USE - The method is useful for generating an alkylbenzene product from a natural oil consisting of palm kernel oil, coconut oil and/or babassu oil (claimed), preferably for the co-production of an alkylbenzene product and biofuel from a natural oil, where: the alkylbenzene is useful as an intermediate in the production of surfactants for detergents; and the biofuel includes diesel or jet fuel.    ADVANTAGE - The method is capable of rapidly generating the renewable alkylbenzene product from the natural oil with good biodegradability, high degree of linearity and increased content of new carbon in an environmentally friendly manner.    DETAILED DESCRIPTION - Generating an alkylbenzene product from a natural oil, comprises: deoxygenating the natural oil consisting of palm kernel oil, coconut oil and/or babassu oil to form a stream comprising paraffins; 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; and separating the alkylbenzenes to provide the alkylbenzene product comprising alkylbenzenes having a 12-13C alkyl group, where the alkyl group is a linear alkyl group for at least 80 mass% of the alkylbenzenes having the alkyl group. INDEPENDENT CLAIMS are included for:    (1) the alkylbenzene product, preferably the linear alkylbenzene sulfonate product produced by the method; and    (2) increasing the amount of modern carbon in detergents, comprising deoxygenating the natural oil consisting of palm kernel oil, coconut oil and/or babassu oil to form a stream comprising paraffins, which have at least 7 mass% of modern carbon, dehydrogenating at least a portion of the paraffins having at least 7 mass% modern carbon 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, sulfonating the alkylbenzene product to form linear alkylbenzene sulfonate, and adding the linear alkylbenzene sulfonate to a detergent formulation.
