A Comparative Study Regarding Hydrodearomatization of an Extraction Gasoline on Ni/Al2O3-SiO2 Catalysts

Abstract:

The removal of benzene, toluene and unsaturated hydrocarbon from the extraction gasoline was achieved by catalytic hydrogenation. The catalyst used was Ni/ Al2O3 - SiO2. The experiments were performed in a continuous fixed bed reactor at 10 bar, 60-150 0C, hydrogen /aromatic hydrocarbon molar ratio of 10 h-1 and gasoline WHSV of 1- 6 h-1. The catalyst behaviour was evaluated through a comparative experiment of a extraction gasoline used at vegetable oil processing and a synthetic mixtures of benzene-hexane, toluene-hexane and benzene-toluene-hexane. The experimental data distinguished an unfavourable influence of toluene on benzene hydrogenation. Keywords : benzen hydrogenation, gasoline, Ni/ Al2O3-SiO2 catalysts
