摘要： 在Al2O3-SiO2-H3PO4-H2O有机胺体系中,利用水热法在陶瓷基片上制得了SAPO-34和SAPO-44分子筛膜.通过XRD,SEM分析对所制备的分子筛膜进行了表征,并对膜制备中SiO2量、HF量以及不同陶瓷基片等影响因素进行了考察.

Abstract: Molecular sieve membranes consisting of SAPO-24 and SAPO-44 molecular sieve crystals have been hydrothermally prepared on the ceramic substrate in the Al2O3-SiO2-H3PO4-H2O-amine system. X-ray diffraction verified the presence of the pure molecular sieve phases on the substrate, and the SEMshowed that the SAPO-34 and SAPO-44 molecular sieve crystals had grown together to form a continuous molecular sieve layer. The influences of silica content, HFcontent, pHvalue in the memberanes formations have been studied.

Key words: SAPO-34 molecular sieve membranes, SAPO-44 molecular sieve membranes, Hydrothermal method, Characterization
