SELECTIVE SYNTHESIS OF AROMATIC HYDROCARBONS FROM SYNTHESIS GAS

Abstract
Aromatic hydrocarbons, whose major components were penta- and hexa- methyl benzenes, were produced with the selectivity of 27% from synthesis gas at 350 °C and under 21 atm with hybrid catalysts containing Pd/SiO2 catalyst and high silica mordenites. Steam treatment of the high silica mordenite, which cause the hydration, promoted the selectivity of aromatic hydrocarbons and suppressed dramatically the coke producing ability of the hybrid catalyst upon synthesis gas conversion.
