烟道气二氧化碳吸附技术的研究进展

The Research Progress of Carbon Dioxide Adsorption Technology in Flue Gas

本文简述了烟道气脱碳技术路线,讨论了燃烧后、燃烧前脱碳技术以及富氧燃烧技术的优缺点,分析了二氧化碳吸附技术,探讨了国内外沸石和活性炭吸附二氧化碳技术的研究动态。研究了活性炭的微孔结构,改性技术以及再生工艺对其吸附性能的影响方式,并提出了合理的建议和展望。

This paper briefly describes the technologieal pathways of carbon dioxide capture, including the advantages and disadvantages of post- combustion capture and pre- combustion capture and oxy- combustion, analyzes carbon dioxide ad- sorption technology and discusses the research progress of zeolite and activated carbon in carbon dioxide adsorption area at home and abroad. The influenees of surface modification, microcellular structure and regeneration on carbon dioxide adsorp- tion are studied, and then some reasonable suggestions and prospects are put forward.
