摘要:
采用2次水热合成法在多孔莫来石支撑体外表面上制备高硅SSZ-13分子筛膜,考察了合成溶胶中的Si/Al比、晶化时间、晶化温度、H2O/SiO2比对合成高硅SSZ-13分子筛膜的单气体渗透性能的影响.高硅SSZ-13分子筛膜的CO2和CH4的单气体渗透性能依赖于合成溶胶中的Si/Al比,Si/Al比越高,越有利于气体分离.其次,合成溶胶中H2O/SiO2比和晶化条件也能够影响分子筛晶体形貌、分子筛层厚度以及分子筛膜的单气体渗透性能.当合成溶胶的摩尔配比为1.000 SiO2:0.100 Na2O:0.100 TMAdaOH:80.000 H2O:0.005 Al2O3,晶化时间和温度分别为48 h和160 ℃时,制备的高硅SSZ-13分子筛膜具有最佳的单气体渗透性能,对CO2的渗透速率可达到3.0×10-7 mol· m-2·s-1·Pa-1),CO2/CH4的理想选择性为39.
Abstract:
High silica SSZ-13 zeolite membranes are prepared on the outer surface of the porous mullite support by secondary hydrothermal synthesis.Effect of synthesis conditions, such as SiO2/Al2O3 and H2O/SiO2 ratios of the precursor synthesis gel,crystallization time and temperature, on the single gas permeation performance of high silica SSZ-13 zeolite membranes are studied in details in this work.The CO2 and CH4 single gas permeation performance of high silica SSZ-13 zeolite membranes are greatly depended on the Si/Al ratio of the precursor gel,the high silica SSZ-13 zeolite membranes shows well gas separation performance for CO2/CH4 separation.The initial synthesis gel with the medium H2O/SiO2 ratio and crystallization conditions are crucial to zeolite crystals morphology, zeolite layer thickness and single gas permeation performance of high silica SSZ-13 zeolite membrane.When the molar composition of the precursor synthesis gel, the crystallization temperature and time are 1.000 SiO2:0.100 Na2O:0.100 TMAdaOH:80.000 H2O:0.005 Al2O3, 160 ℃ and 48 h,the CO2 permeances is 3.0×10-7 mol ·m-2·s-1·Pa-1and CO2/CH4 separation factor of the as-synthesized SSZ-13 zeolite membrane is 39.
