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 o C 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

... ution (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.
