| 英文摘要 | the catalytic performance of mo-based catalysts supported on various zeolites has been studied for methane aromatization in the absence of oxygen in a fixed-bed continuous-flow quartz reactor, and their catalytic properties are correlated with features of zeolite structure. it was found that h-type silica-alumina zeolites, such as zsm-5, zsm-8, zsm-11 and beta possessing two-dimensional structure and pore diameter equaling the dynamic diameter of a benzene molecule (about 6 angstrom) simultaneously, are fine supports for methane activation and aromatization catalysts. among them, moo3/h-zsm-11 has the best activity and stability; for instance, a methane conversion of 8.0% and selectivity higher than 90% was obtained at 973 k. the catalytic performance of moo3/h-zsm-8 is somewhat lower than that of moo3/h-zsm-5, while activity of moo3/h-beta is lower than that of moo3/h-zsm-8. catalysts supported on h-mcm-41 and h-sapo-34 exhibit low activity for methane aromatization and those supported on h-mor, h-x and h-y give only a little amount of ethylene. over moo3/h-sapo-5 and moo3/h-sapo-11 no hydrocarbons were detected. |
