项目摘要
Zeolites are crystalline alumino-silicate, and widely used as catalysts and adsorbents. MFI-type zeolite has fine pores within its crystals, the diameter of which is almost the same as the molecular size of benzene. Hence, the zeolite shows high molecular-sieving effect. When the zeolite is succeeded to be prepare in the shape of membrane, the membrane can enable to realize new separation and simultaneous reaction and separation with high performance. The main objective of this project is to development of MFI-type zeolite catalytic membrane, and to apply it to high separation and simultaneous reaction and separation processes.In fiscal year of 1997, we conducted the following research work :MFI-type catalytic membrane was succeeded to prepared without any pin-holes by a new method, well-mixed hydrothermal synthesis. This membrane was found to show high proof against thermal and mechanical shocks and to be used at above 773 K.The separation factor of para- to ortho-isomers of xylene an … More d diethyl-benzene was 3 and 7, respectively.In fiscal year of 1998, the membrane was applied to high separation and simultaneous reaction and separation processes, and the following results were obtained :1) Selective permeation of water from concentrated acetic acid : only water can permeate through the membrane under the conditions of temperature from 343 K to 363 K and the concentration of acetic acid from 20 to 98%.2) Selective separation of hydrogen from mixtures of hydrogen with nitrogen, oxygen and carbon dioxide : the separation factor of hydrogen to the other gas was found to be about 100 in the flow system at 483 K.3) Simultaneous reaction and regeneration : Reaction of methanol is a consecutive reaction, such as methanol (]SY.tri-substituted left.[) ether (]SY.tri-substituted left.[) olefin (]SY.tri-substituted left.[) paraffin+aromatics. Methanol diffuses through the catalytic zeolite membrane undertaking the reaction. When methanol is converted to olefin, they pass completely through the membrane, attaining high selectivity of olefin. The selectivity of olefin was enhanced up to 85% as compared with only 7% for the usage of conventional fixed bed reactors. Less
沸石是结晶硅铝酸盐,广泛用作催化剂和吸附剂。MFI型沸石的晶体内具有细孔,其直径几乎与苯的分子尺寸相同,因此沸石表现出高分子筛分性。当沸石成功制备成膜状时,该膜能够实现新型分离以及高性能的同时反应和分离。开发MFI型沸石催化膜,并将其应用于高分离度、同时反应和分离的过程。1997财年,我们进行了以下研究工作:成功制备了无针孔的MFI型催化膜通过一种新方法,即充分混合的水热合成,该膜具有良好的抗热冲击和机械冲击能力,可在 773 K 以上的温度下使用。二甲苯和d二乙苯的邻位异构体分别为3和7。 1998财年,该膜应用于高分离度、同时反应和分离过程,得到以下结果:1)选择性渗透浓乙酸中水的透过率:在温度343K~363K、乙酸浓度20~20℃的条件下,只有水能透过膜。 98%.2) 从氢气与氮气、氧气和二氧化碳的混合物中选择性分离氢气:在 483 K 的流动系统中发现氢气与其他气体的分离系数约为 100。3) 同时反应和再生:甲醇的反应为连续反应,如甲醇(]SY.三取代左.[)醚(]SY.三取代左.[)烯烃(]SY.三取代左.[)烷烃+芳烃通过催化沸石膜扩散进行反应,当甲醇转化为烯烃时,它们完全通过膜,获得了高的烯烃选择性。与使用传统固定床反应器仅 7% 相比,提高了 85%。
