Riassunto

近年来，温室气体排放所造成的全球变暖问题已成为国际普遍关注的焦点之一，进行全球性大规模CO2减排势在必行。在众多燃烧后CO2捕集技术中，采用碱金属基固体吸收剂脱除烟气中的CO2，被认为具有广阔的应用前景。然而，由于燃煤烟气中存在一定量的杂质气体SO2，且常规的负载型钾基吸收剂的CO2吸收能力较差，使得碱金属基吸收剂在循环运行过程中很快失效而影响吸收剂的脱碳特性及使用周期，从而阻碍了该技术的工业化发展。针对该技术难点，开展了相应的研究工作。(1)探明了钾基吸收剂在燃煤烟气中的脱碳及失效规律，获得了相应的动力学参数；(2)通过优化运行参数，提出了两级串联运行脱碳技术。在20小时的稳定运行中，脱碳效率维持在96%以上；20小时后，吸收剂失效率控制在约1.2%；(3)系统研究了吸收剂在燃煤烟气中同时与CO2和SO2的竞争反应机制以及吸收剂失效的机理与途径，结合动力学参数，建立相应的竞争模型；(4)通过对吸收剂失效规律及机理的认识了解，制备了能有效缓解SO2影响的钙基改性的钾基吸收剂。该吸收剂对CO2吸收能力加强、对SO2抵制能力加强、长期脱碳运行能力稳定；(5)制备了胺基改性的新型有机－无机复合型K2CO3-Amine-基固体吸收剂（KN），该吸收剂脱碳能力远超过常规的钾基吸收剂，且热稳定性也优于常规的有机固体吸收剂，吸收剂脱碳能力的加强也是有效缓解吸收剂失效的一种有效途径之一。
