Highly Efficient Oxidative Coupling of Methane over LiCl-B2O3/MnO2 and Li2SO4-MnxOy/TiO2 Catalysts

摘要/Abstract

摘要： Because of the ever-increasing consumption of crude oil, the role played by the natural gas as a raw material has become more and more important in chemical industry and the potential of methane used as a source for the production of ethylene has attracted much attention. In this paper, the LiCl- B2O3/MnO2 and Li2SO4-MnxOy/TiO2 catalysts for Oxidative Coupling of Methane (OCM) have been studied, and the results show that the catalysts exhibit high activity and selectivity. Furthermore, The in uence of the components in the catalyst and the reaction conditions on OCM performance has been studied and a possible active new component, cubic Li4B7O12Cl, has been found.
