抄録

In the methanol-to-olefins (MTO) reaction, product flexibility is important for meeting the fluctuating chemicals demands. In this paper, the catalytic performance of recently reported zeolites having 12-ring pores, such as boroaluminosilicate CON-type zeolite ([Al,B]-CON), MCM-68, and YNU-5 zeolites, in the MTO reaction was compared to understand the relationship between zeolite framework and product selectivity. The catalytic performance of the synthesized zeolites was compared with that of Beta, mordenite, and ZSM-5. The highest selectivities for propylene and butylenes were achieved over MCM-68. The highest propylene-to-ethylene ratio in the products was obtained over [Al,B]-CON. ZSM-5 and [Al,B]-CON exhibited a superior ability to suppress coke formation compared to Beta, mordenite, MCM-68, and YNU-5.
