SAPO-34在多相催化中的应用进展

Application of SAPO-34 in Heterogeneous Catalysis

SAPO-34分子筛因在甲醇转化制备轻烯烃以及NH3选择性催化两项应用中表现优异而备受关注,但失活过快的缺点限制了其进一步应用。从改良SAPO-34角度阐述为优化工艺流程取得的众多研究成果,指出现代表征技术结合计算机模拟有利于更好地理解SAPO-34性能提升的原因。

SAPO-34 molecular sieve has attracted much attention because of its excellent performance in methanol conversion to light olefins and NH3 selective catalysis.However,its rapid deactivation limits its further application.From the perspective of improving SAPO-34,many efforts to optimize the process are expounded.At the same time,it is sated that the combination of modern characterization technology and computer simulation is the main experimental technical means to better understand the performance improvement of SAPO-34.
