Abstract

Abstract: Not only did the ZSM-5/mordenite (ZSM-5/MOR) composite zeolite catalyst give h igh activity for the conversion of mixed C4 hydrocarbons, but also it possesse d high selectivities to ethylene and propylene, to benzene and toluene. The yiel d sum of benzene and toluene increased with the content of ZSM-5, and even it w as much greater than that over bare ZSM-5 zeolite. At the reaction temperature of 625 ℃ the yield sum of benzene and toluene could reach as high as 44.5%.

Key words: ZSM-5 zeolite, mordenite, composite zeolite, mixed C4 hydrocarbon, ethylene, propylene, aromatization, benzene, toluene
