A method for the production of a D-3-D-11 alkane-aromatic hydrocarbon (HC) fraction by the coconversion of a mixture of alcohols simulating biomass fermentation products and vegetable oil without using molecular hydrogen has been developed. A characteristic feature of this method is the occurrence of coupled alcohol aromatization reactions evolving hydrogen consumed for the hydrogenation of unsaturated HC moieties formed from fatty acid triglycerides in the presence of a pilot sample of the Pd-Zn/TsVM/Al2O3 catalyst. It has been found that the optimum amount of vegetable oil in the feed mixture is 25-50 vol %; this amount provides the target fraction yield of up to 95% on a fed carbon basis.
