摘　　要：AFI(SAPO-5)和CHA(SAPO-34、SAPO-44和SAPO-47)型分子筛是两类有广泛应用的硅铝磷分子筛。两类分子筛经常共晶生长或竞争性生长。控制晶化条件、合成方法和合成初始溶胶组成,能够选择性合成纯相AFI和CHA型分子筛。本文主要从陈化时间、晶化时间、晶化温度和加热方式、合成方法、合成初始溶胶组成等方面,介绍了选择性合成AFI和CHA型分子筛的方法。扩展选择性合成AFI和CHA型分子筛的方法,不仅有利于深入理解SAPO-n分子筛的形成机理,还有利于AFI和CHA型分子筛的工业化生产。Abstract： AFI （ SAPO - 5 ） and CHA including SAPO - 34, SAPO - 44 and SAPO - 47 are two kinds ofsilicoaluminophosphates molecular sieves which are used extensively in many areas. It is observed that AFI and CHA areeutectic growth or competitive growth. The selective synthesis of AFI and CHA molecular sieves has been achieved by thecrystallization temperature, initial gel composition, and synthetic method. The effect of aging time, crystallization time,crystallization temperature and heating method, synthetic method, initial gel composition, and so on, was mainlysummarized, on the selective formation of AFI and CHA molecular sieves. The methods for selective synthesis of AFI andCHA were extended, which was not only helpful to understand the formation mechanism of SAPO-n molecular sieves, butalso beneficial to the industrial production of AFI and CHA.
