中文摘要	近年来,全球性气候变暖已经严重威胁到人类社会、生存环境以及经济的发展,CO2减排问题刻不容缓。整体煤气化联合循环技术(IGCC)同燃烧前脱碳技术的联合应用,有望实现CO2的近零排放,成为当前研究热点之一。本文介绍了燃烧前脱碳技术的发展现状,简述了吸收法、吸附法、膜分离法等CO2分离方法的优缺点及其适应性,为回收利用CO2提供了技术依据。根据IGCC排放源特征,文章重点阐述了几种典型物理分离工艺特点及其在燃烧前脱碳技术的应用范围和前景,从新型高效CO2吸收剂的选择与应用、再生工艺的优化与创新以及耦合工艺的开发3个方向对CO2物理吸收法分离成本降低研究进行了论述,并对燃烧前脱碳技术所面临的挑战及其发展动向进行了深入讨论。; Global warming and CO2 emission reduction has become one of the most critical issues in recent years,due to further deterioration of natural environment,economic development and even survival of mankind. A promising approach for near-zero CO2 emission power plants to be realized within the near future is the IGCC technology(integrated gasification combined cycle) with pre-combustion CO2 capture. In order to provide a technical basis,this paper introduces the current situation of pre-combustion technology and makes a comparison of various CO2 recovery methods,such as adsorption,membrane and absorption process. On the basis of IGCC characteristics,the paper pays special attention to the application range and prospect of existing solvent-absorption technologies,and makes an analysis to point out the possibility of cost reduction from three aspects:selecting a new efficient solvent,optimizing traditional regeneration process,and developing certain coupling technologies. Furthermore, the challenges and trend of decarbonization technology development are discussed.
