Energy-Efficient coaromatization of methane and propane

Development of highly effective catalysts for one-stage conversion of methane with high selectivity to valuable products and energy efficiency will provide an efficient way to utilize natural gas and oil-associated gases and to protect environment. In recent years,there have been many efforts on direct catalytic transformations of methane into higher hydrocarbons by feeding additives together with methane under non-oxidative conditions. This paper reviewed the ad-vances in recent research on non-oxidative aromatization of methane in the presence of propane over different modified HZSM-5 cata-lysts. The thermodynamic consideration,the isotope verification and the mechanism of the activation of methane in the presence of propane are discussed in the paper in detail.
