The pseudocubic plate-like SAPO-34 molecular sieves were synthesized using composite templates, and were characterized by XRD, SEM, BET and NH3-TPD. The as-synthesized SAPO-34 zeolites displayed BET surface areas up to 720 m2/g, moderate acidity. The activities of catalysts in the process of methanol to olefin (MTO) by using the obtained SAPO-34 molecular sieves were investigated. The catalysts exhibited relative longer life span, methanol conversion was over 99% and the total selectivity to ethylene and propylene could be over 80%.
