摘要
介绍了SAPO分子筛在烯烃异构、烷烃异构、芳烃异构、异构脱蜡等化工过程的最新应用;综述了通过引入合适的金属离子对SAPO分子筛的酸性和孔道结构进行调节,有利于烃类异构化反应;认为有效提高SAPO分子筛的稳定性,是急需解决的问题。
In this paper, the latest advances in the application of silicoaluminophosphate （SAPO） molecular sieves to isomeric catalysis are reviewed. The modification of SAPO with suitable metal ion to adjust pore structure and the distribution of acid is introduced. It is an important and urgent problem to find some good ways to improve the stability of SAPO molecular sieves.
