燃煤电站CO_2捕集技术研究现状及前景展望

由CO2等温室气体引发的温室效应对全球环境造成了显著影响,这使得CO2捕集和储存技术受到了越来越多的重视。燃煤电厂是CO2重要的排放源,同时也是将来CO2捕集技术的主要应用对象。本文介绍了4种主要的燃煤电厂CO2捕集技术,包括燃烧前脱碳技术、燃烧后CO2捕集技术、富氧燃烧技术和化学链燃烧技术,分析了这些技术各自的优势和亟待解决的问题,并从经济性、先进性和成熟度3个方面对这些技术进行了比较,最后对我国CO2捕集技术发展前景进行了展望。

Research Status and Prospect for Coal Fired Power Plant with CO_2 Capture

Environmental issues due to emissions of CO2 and other greenhouse gases from combustion of fossil fuels have become a global problems,while the subject of CO2 capture and storage is calling more and more attention.In a global context,among all the industrial emitting CO2,fossil-fueled power plants generate the largest proportion.In this paper,the four main CO2 capture technologies discussed include post-combustion,pre-combustion,oxy-fuel combustion and chemical-looping combustion techniques.Various separati...
