| 英文摘要 | the catalytic stability of zsm-5 zeolite in butene aromatization was improved by the treatment of zsm-5 zeolite with sodium hydroxide solution of appropriate concentration. by characterizing pore structures, the acidity of the catalyst and the coke amount, we found that alkali-treatment of zsm-5 led to a formation of new mesopores resulting from a preferential removal of silicon species, while the intrinsic micropores remained unchanged. as for the acidity, the amount and properties of acid sites exhibited a slight change on the alkali-treated zsm-5 zeolites. in addition, the alkali-treatment to zsm-5 zeolite led to only a little reduction in the amount of coke during the butene aromatization. but a portion of coke was deposited in the newly created mesopores because of the alkali-treatment and the formation of coke in the micropores was found to be reduced. these changes can suppress the channel blockage of zsm-5 zeolite by the coke deposits during butene aromatization. the variation of the coking location was the main reason for the favorable enhancement in the reaction stability during butene aromatization.
