| 英文摘要 | re/hzsm-5 is also a better catalyst for methane aromatization compared with mo/hzsm-5 catalyst. the best re loading is 10%. the original performance of re/hzsm-5 is much better than mo/hzsm-5, but its lifetime is much shorter than the latter. the acidity of the catalyst, the change of framework aluminum after impregnation of re species and the reduction capacity of re/hzsm-5 were investigated by using nh3-tpd, mas nmr and h-2-tpr. the results indicated that the acidity of the catalyst also plays a key role in the reaction, and the catalytic performance of the catalyst is probably proportional to its acidity. but it is not that the stronger the acidity is and the more the amount of acid sites and the better the performance of the catalyst. after impregnation of re, the metal species interacts with framework aluminum intensively and causes the dealumination of the catalyst. re/hzsm-5 tends to be reduced by h-2 at lower temperature compared with mo/hzsm-5, and the active species after reduction is singleness. |
