一种抗CO2腐蚀的双相混合导体透氧膜材料及其制备方法
摘要：
本发明公开了一种抗CO2腐蚀的双相混合导体透氧膜材料及其制备方法，该材料由以下的组成及重量百分比：Ce1-xLnxO2-δ氧化物60％；Pr1-ySryCo1-z-wFezMwO3-δ氧化物40％；其中，Ln＝La、Pr、Nd、Sm、Gd，0≤x≤0.2；M＝Ti、V、Nb、Zr、Mo、Ta，0＜y＜1，0.2≤z≤0.5，0≤w≤0.2，其制备方法为：分别将一定量各金属元素的硝酸盐或氧化物溶于硝酸水溶液或去离子水中并与溶有乙二胺四乙酸和一水合柠檬酸的溶液混合，待水分挥发后，经两次焙烧得到Ce1-xLnxO2-δ粉体和Pr1-ySryCo1-z-wFezMwO3-δ粉体，将两种粉体混合、研磨，在一定压力下成型获得坯体，再在1150～1250℃焙烧5～10小时，得到双相混合导体透氧膜片，该方法制备的双相混合导体透氧膜在纯CO2气氛下不仅能够稳定运行，而且能保持较高的透氧量，透氧量达到0.29mL·min-1·cm-2。
摘要（英）：

The invention discloses a CO2 corrosion resistant biphase mixed-conducting oxygen permeable membrane material and a preparation method thereof. The material is composed of the following components by weight percentage: 60% of Ce1-xLnxO2-delta oxide; and 40% of Pr1-ySryCo1-z-wFezMwO3-delta oxide, wherein Ln=La, Pr, Nd, Sm, Gd, x is greater than or equal to 1 and smaller than or equal to 0.2, M=Ti, V, Nb, Zr, Mo, Ta, y is greater than 0 and smaller than 1, z is greater than or equal to 0.2 and smaller than or equal to 0.5, and w is greater than or equal to 0 and smaller than or equal to 0.2. The preparation method includes: dissolving a certain amount of nitrate or oxide of metal elements in a nitric acid aqueous solution or deionized water respectively, and performing mixing with solution with dissolved ethylenediaminetetraacetic acid and citric acid monohydrate, volatilizing moisture, then conducting roasting twice to obtain Ce1-xLnxO2-delta powder and Pr1-ySryCo1-z-wFezMwO3-delta powder, mixing the two powder and performing grinding, conducting moulding under certain pressure to obtain a blank, and then performing roasting at 1150-1250DEG C for 5-10h, thus obtaining a biphase mixed-conducting oxygen permeable membrane sheet. The biphase mixed-conducting oxygen permeable membrane prepared by the method provided by the invention not only can operate stably under a pure CO2 atmosphere, but also can maintain a high oxygen permeation rate up to 0.29mL.min<-1>.cm<-2>.
