摘要 在多孔 α- Al2 O3陶瓷管的外表面水热合成 Na Y型沸石膜 ,用XRD及 SEM表征所合成的膜。并将合成出的膜用于分离二氯乙烷和氮气的混合物 ,考察了不同压力差对分离效果的影响。实验结果表明 ,将渗透压差控制在 50 k Pa,既可保证有较高的渗透率 ,又有一定的分离因数。 The present article introduces the author's method of preparing Y-type Zeolite membrane by hydrothermal processing on the outer surface of a porous α-Al_2O_3 support tube. The membrane prepared in this way is characterized by XRD and SEM. The result gained from our method shows that the Y-type zeolite membrane keeps the property ob being continuous, integrated and dense. Tested by the adsorption of zeolite NaY, the zeolite NaY showed it had stronger adsorption to polar gas than non-polar gas, thus, demonstrating its adsorption of dichloroethane on zeolite NaY is advantageous over N_2. In addition, it is necessary to point out that Y-type zeolite membrane can be used to separate the mixture of dichloroethane and N_2. By Through experiments on the gas penetration, the author has also made a thorough study and analysis of the influence of the Y-type zeolite membrane on α_(C_2H_4Cl_2/N_2) at various differential pressures was. The experimental results indicate that the separation factors were increased with the increase of differential pressures of penetrability and reached the maximum on the 50 kPa, which was 17.7.
