英文摘要: The catalytic performance for methane aromatization in the absence of oxygen over various supported zeolite catalysts was studied on a continuous flow fixed bed reactor, It is found that I-I-form silica-alumina zeolites with two dimensional space structure, such as ZSM-5, ZSM-8 and ZSM-11 whose pore size is very near to the dynamic diameter of benzene (0. 6 nm), are fine supports for methane aromatization, among which 3%MoO3/HZSM-11 possesed the highest activity and stability, the maximum conversion of methane and selectivity to benzene are 8. 0% and 90. 9% respectively. The catalytic performance of MoO3/HZSM-8 and 3%MoO3/H-beta are relatively lower than that of 3%MoO3/ HZSM-5, The catalysts supported on HMCM-41 and HSAPO-34 have a very low activity for the reaction and over the catalysts of MoO3/HMOR, HX and HY only a small amount of ethylene is produced, while hydrocarbons have not been detected over the catalysts of MoO3/HSAPO-5 and MoO3/HSAPO-11.
