摘    要:文章以三嵌段共聚物P123为模板剂、正硅酸乙酯为硅源,水热合成了介孔分子筛SBA-15,以3-丙胺基三乙氧基硅烷(APTES)为氨基化剂,采用浸渍法将其嫁接到SBA-15孔内,形成氨基化的SBA-15用于吸附电厂尾气CO2。通过氮等温吸附-脱附、XRD、TEM等测试技术对其进行了表征,考察了改性前后SBA-15的吸附性能。结果表明:改性前后的SBA-15对电厂尾气中CO2均具有良好的吸附性能,改性的SBA-15比合成的SBA-15吸附性能要好。

Abstract:Mesoporous molecular sieves SBA - 15 was synthesized by conventional hydrothermal process using tetraethylorthosilicate(TEOS)as silicon source and triblock copolymer P123 as template. CO2 sorbent were prepared by introducing(3 -Aminopropy) triethoxysilane (APTES) into SBA - 15 using a post - synthetic impregnation method. The synthesized sorbent was characterized by N2 adsorption - desorption, X - ray diffraction (XRD) and transmission electron microscopy ( TEM ). The adsorption properties of SBA - 15 and modified SBA - 15 were investigated under different and same temperatures. The results indicated that SBA - 15 and modified SBA - 15 both have a good adsorption performance, at the same temperature, the modified SBA - 15 shows better adsorption performance than the synthesis SBA - 15.
Keywords:SBA - 15  flue gas from power plant  CO2  amino - functionalized  adsorption
