用原位水热合成法在α Al2 O3 陶瓷管上合成出MFI型分子筛膜 .采用超声清洗的方法表征了分子筛晶体的附着强度 ,并用XRD和SEM等手段对分子筛膜进行了表征 .渗透数据表明 ,气体透过膜时不遵从努森扩散机理 ;此分子筛膜具有分子筛分作用 ,基本无缺陷 The in-situ hydrothermal synthesis method was used to synthesize MFI zeolite membrane on α Al2 O3 ceramic tube.The ultrasonic cleaning method was used to characterize the attachment strength of the zeolite crystal and the molecular sieve membrane was characterized by XRD and SEM. , Gas does not follow Knudsen diffusion mechanism when passing through the membrane; this molecular sieve membrane has the molecular sieve effect, with essentially no defects
