In this paper, the advantages and disadvantages of conventional hydrothermal synthesis, microwave-assisted synthesis, dry gel conversion synthesis and solvent-free synthesis were compared and analyzed. The influences of preparation parameters such as template agent, Si/Al ratio, H₂O/Al₂O₃, silicon source, aluminum source and metal modification on the physicochemical properties and catalytic performance of SAPO-34 zeolites were emphatically introduced. Its catalytic applications such as methanol to light olefins, ammonia selective catalytic reduction of NO_x and hydrocarbon catalytic cracking to light olefins were briefly summarized. It provides some reference significance and research ideas for the design and preparation of new and efficient SAPO-34 zeolites. 查看全文查看/发表评论下载PDF阅读器 相关附件：版权转让声明书 -->
