摘　　要：综述了SAPO-34分子筛催化低碳物转化制低碳烯烃(甲醇、二甲醚、卤化烷烃制烯烃、乙醇脱水制乙烯)、C_4～C_8直链烯烃/烷烃裂解制低碳烯烃、烷烃氧化或直接脱氢反应制烯烃、催化烃类或H_2选择性还原NO_x、制备膜分离材料以及在发光体材料等领域中的应用。系统分析sAPO-34分子筛在各领域应用进展,有利于理解材料的物化性能对其催化性能、热稳定性及水热稳定性、选择性渗透和分子筛分离性能的影响,有利于实现对SAPO-34分子筛的认识取得突破性进展,拓展SAPO-34分子筛应用领域,并为其他催化材料的设计提供借鉴。The application of SAPO-34 molecular sieves in catalyzing light carbon compounds to light ole-fins（ including methanol, dimethyl ether, methyl halides to olefins, ethanol dehydration to ethylene）, C4-C8 alkene and alkane cracking to propylene, paraffin oxidation or direct dehydrogenation to olefins, the selective reduction of NOx by hydrocarbon or H2, preparing membrane separation materials and serving as carrier for photoluminescence materials were reviewed. The systemic analysis for SAPO-34 application in different fields were beneficial to understanding the effects of physical and chemical properties such as medium acid properties, distinct small pore structure characteristic, abundant micro-pore and great specific surface area on catalytic performance, thermal stability and hydrothermal stability, selective permeability and molecular sieve separation characteristic, in order to gain breakthrough progresss in apprehending SAPO-34 molecular sieves and also help to expand SAPO-34 application fields and provide references for designing other catalytic materials.
