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.
