摘要
通过水热反应和离子交换改性,成功地合成了CaCHA分子筛。采用热重法测定了不同温度下CaCHA对CO2、N2和O2的吸附性能。随着温度的升高,CaCHA的吸附量逐渐减小。当温度升高到393K时,达到了CO2/N2和CO2/O2的最大吸附选择性。
CaCHA zeolite was successfully synthesized by hydrothermal reaction and ion exchange modification. The adsorption properties of CaCHA on CO2, N2 and O2 at different temperatures were determined by thermogravimetry. T he adsorption capacity of CaCHA decreases with the increase of temperature. When the temperature rises to 393K, the maximum adsorption selectivity of CO2/N2 and CO2/O2 is achieved.
