25-O-05-Benzene alkylation with alkanes over modified MFI catalysts

Abstract

Publisher Summary This chapter discusses benzene alkylation with alkanes over modified MFI catalysts. It describes benzene alkylation with ethane, propane, and i-butane on acidic H-MFI zeolite with silicon dioxide/alumina (SiO 2 /A1 2 O 3 ) ratio of 104; mixed (H-MFI + Pt/CeO2) catalytic systems and Pt/H-MFI bifunctional catalysts with platinum content of 0.3%. In some of the experiments, hydride-forming metals (M) are added to the catalytic systems to ensure H 2 removal from the reaction zone. The conversion of alkanes and the selectivity to the products of direct addition is found to increase in the following order of catalytic systems: H-MFI 2 H 6 3 H 8 4 H 10 ; their alkylating ability is found to increase in the reverse order.
