A Study of the Catalysts in Oxidative Coupling of Methane

Abstract

Abstract: The activity, selectivity and life time of alkali metal salt catalysts carried on the surface of samarium oxide and on that of other metalic oxides used in oxida-tive coupling of methane are reported here. Meanwhile, the influence of temperature, partial pressure of methane and molar ratio of methane to oxygen on the activity and selectivity of the catalysts are determined. The results of experiments show that the most important ones are lithium chloride carried on nickel oxide and manganese dioxide. They can directly convert methane to ethylene. The output of ethylene increase to 26% and 28%.

Key words: Methane, Oxidative coupling
