METHANE DIRECT CONVERSION TO ETHENE OVER Mo/SAPO-34 CATALYSTS

We have studied the methane activation in non-oxidative condition1,2],and have shown the possibility of direct methane conversion to aromaticsover Mo/HZSM-5.Ethene is regarded as the initial product of the reaction.We thus pay attention to the selective production of ethene and low hydro-carbons from methane directly.The molecular sieve HSAPO-34(SP) waschosen as catalyst support,which has the framework topology of naturalchabazite,and has been shown to convert methanol selectively to Cl~ C3 hy-drocarbons3].The framework Of SP contains a three-dimensional channel
