| 英文摘要 | hmcm-22 zeolite with variable sio2/al2o3 ratios has been successfully synthesized and used as support of molybdenum based catalyst in methane dehydroaromatization. effect of sio2/al2o3 ratio on the catalytic performance of mo/hmcm-22 catalysts was studied, and results show that methane conversion and benzene selectivity increase with the decrease of sio2/al2o3 ratio, and reach maximum on mo/hmcm-22 catalyst with sio2/al2o3 ratio of 25. further increasing sio2/al2o3 ratio results a decrease of activity and benzene selectivity. al-27 mas nmr spectroscopy and nh3-tpd techniques were applied to characterize the structure-property relationship of the catalyst. the catalytic performance of mo/hmcm-22 catalysts in methane dehydroaromatization has been correlated with the bronsted acidity of hmcm-22 zeolite supports, which may promote not only the methane activation on the mo carbide sites of mo/hmcm-22 catalysts, but also further oligomerization of the chx surface species towards aromatics products in the reaction. |
