摘要：
The oxidative methylaion of toluene with methane to ethylbenzene and styrene proceeded over basic Y type zeolite catalyst at 1023K. KY was prepared from NaY raw powder by exchange with 0.5M KOH aqueous solution at 363K. Loaded KY were prepared by impregnating aqueous solutions of LiNO3 and CsNO3 onto KY zeolite. Only KY zeolite showed very low C-8-yield and selectivity. Addition of alkali-metal oxides to the KY zeolite increased greatly the catalytic activity. The Cs2O(6wt% Cs2O)/KY catalyst gave the highest C-8 yield of 32.2% with selelectivity of 60.9%.
