摘要(Abstract)：

针对当前有机胺法吸收剂在工业运行过程中降解失效的现状，以AEEA复合试剂为测试对象，采用玻璃搅拌反应釜进行吸收/解吸反应，联合高压反应釜开展氧化降解测试，研究复合胺吸收剂的降解性能。按照质量比例20：1，20：3，20：5，在AEEA试剂中分别添加DEA、PZ、MDEA组成9种总质量分数都为10%的二元复配溶液，研究对比了9种复配胺溶液吸收负荷、吸收速率、再生速率、再生率，优选出三种最优复配吸收剂，吸收效果由高到低排列：20：5 AEEA+PZ > 20：1 AEEA+DEA > 20：3 AEEA+MDEA。对三种混合胺溶液进行连续6次吸收和解吸，研究考察了降解过程：经6次循环实验后，以AEEA为主的三种复配溶液及AEEA单胺溶液胺降解程度由大到小排序为：20：1AEEA+DEA > AEEA > 20：3 AEEA+MDEA > 20：5 AEEEA+PZ，得出AEEA与DEA复配会促进胺降解，而AEEA与PZ复配则会抑制胺降解。
