摘　　要：采用原位水热合成法在多孔α-Al2O3上制备了CoAPSO-5分子筛膜;通过XRD和SEM检测,证明所合成的CoAPSO-5分子筛膜致密、均一、厚度20μm无取向;通过气体渗透法检测所合成的分子筛膜为无缺陷;同时,考察了CoAPSO-5分子筛膜对CO2/CH4混合气的分离效果,渗透分离结果显示,在渗透压差分别为0.3和0.5 MPa时,CO2/CH4的真实分离系数分别为4.86和5.29。The CoAPSO-5 membrane on the α-Al2O3 substrate was synthesized by using in situ crystallization.According to detection results of scanning electron microscopy（SEM） and X-ray diffraction（XRD）,the 20 μm thick membrane was composed of well-intergrown CoAPSO-5 crystals,which were tightly covered on the α-Al2O3 substrate in random orientation.The gas permeation measurements revealed the resulting membrane was of high-quality with few non-zealitic pores.In addition,the separation property of CO2/CH4 through the synthesized CoAPSO-5 membrane was investigated.When the osmotic pressure was 0.3 MPa and 0.5 MPa,the real separation factor of CO2/CH4 was 4.86 and 5.29 respectively.
