摘要:
采用二次生长法在α-Al2O3四通道中空纤维支撑体外表面合成SAPO-34分子筛膜,用于渗透汽化脱水分离。考察操作温度对分子筛膜渗透汽化性能的影响,并研究渗透汽化过程中膜结构性能的稳定性。结果表明:采用球磨晶种诱导合成出了高质量的SAPO-34分子筛膜,75 ℃下膜在异丙醇(90%)-水(10%)体系中,分离因子达到3 600,渗透通量为3.34 kg/(m2·h); 在乙醇(90%)-水(10%)体系中,膜的分离因子最高为419,渗透通量为1.19 kg/(m2·h)。SAPO-34分子筛膜具有良好的渗透汽化分离稳定性和耐酸性能。
Abstract:
SAPO-34 zeolite membranes were prepared on external surface of four-channel α-Al2O3 hollow fibers for pervaporation dehydration by secondary-growth method.Influence of operating temperature on pervaporation performance of the membranes was investigated.The structure stability of the membranes was also evaluated for pervaporation dehydration.Results showed that high-quality SAPO-34 zeolite membranes were prepared with the induction of ball-milled seeds.The membrane exhibited a high separation factor of 3 600 and permeation flux of 3.34 kg/(m2·h)in dehydration of isopropanol(90%)-water(10%)mixture and performed a separation factor of 419 and permeation flux of 1.19 kg/(m2·h)in dehydration of ethanol(90%)-water(10%)mixture at 75 ℃.The membranes showed good operating stability and acid resistance during pervaporation dehydration.
