摘要(Abstract)：

随着全球气候变化愈演愈烈，碳捕集、利用与封存技术（carbon capture, utilization and storage,CCUS）成为实现“碳中和”目标的关键手段。针对传统吸收剂在CO_2捕集中存在的运行稳定性差和再生能耗高等问题，开发了一种新型贫水复配吸收剂，该吸收剂以叔丁氨基乙醇（TBAE）为主要成分，通过组合不同配比的胺和稳定剂优化配比，按总胺质量分数30%混合，以质量分数为30%的传统吸收剂乙醇胺（MEA）为参考标准，进行了CO_2吸收-解吸性能、腐蚀情况和小试放大实验的测试研究，旨在提高CO_2的吸收容量和解吸速率的同时降低再生能耗和提升溶剂在装置中稳定运行的能力。实验结果表明：当配方为20%（质量分数，下同）TBAE+10%3-甲胺基-1-丙醇+50%N-甲基吡咯烷酮时，其饱和CO_2吸收量为3.10 mol/L，循环吸收量为2.97 mol/L，腐蚀速率为0.016 2 mm/a，再生能耗为4.00 GJ/t；与质量分数30%MEA吸收剂相比，CO_2饱和吸收量提高了12.3%，循环量提升了22.7%，腐蚀速率降低了60.3%，再生能耗降低了36%。该新型贫水复配吸收剂性能良好，并在10 t/a碳捕集小试装置中长时间稳定，且较低能耗的运行为该吸收剂将来投入工业使用积累了坚实基础。
