Abstract

In order to reduce the cost, a mixed template of BTMA+ and TMADA+ was used to synthesize SSZ-13 zeolite. The effects of the compositions of the mixed template on structure and morphology were characterized by XRD, SEM. The catalytic performance of prepared SSZ-13 was investigated in a fixed-bed reactor at 450 oC for the methanol-to-olefin reaction ,the weight hourly space velocity (WHSV) was 1.75 h-1. The results show that cubic SSZ-13 crystals with good crystallinity and small size distribution (the average particle size of 0.3 um) was synthesized with the n(TMADA+)/n(TMADA++BTMA+) is 0.3. In the methanol-to-olefin reaction, The yield of olefin can reaches 88%, and the lifetime of the catalyst is above 200min.
