摘要
Abstract
SAPO-44 molecular sieves with different Si contents were hydrothermally synthesized by using cyclohexylamine as the template. The samples were characterized by XRD, SEM, NH3-TPD and tested as the methanol-to-olefins (MTO) catalysts. The results showed that, as the Si/Al ratio increased, the relative degree of crystallinity and the surface acidity increased, and some non-cubic crystals were found out. At the same time, the initial selectivity of olefins decreased and the propylene/ethylene mass ratio increased with the Si content of SAPO-44 sample.关键词
