二氧化碳回收及利用分析

摘要

介绍了二氧化碳的来源、特点及用途等,阐述了典型二氧化碳回收技术:物理吸收法,化学吸收法,吸附分离法,膜分离法的原理和工艺特点,对二氧化碳常用的四种回收利用技术的优缺点进行了比较分析.通过对二氧化碳的来源、用途及经济性分析,结果表明:二氧化碳的回收利用,重点应放在减少化石性燃料的使用及提高CO2 的分离回收技术和综合利用上,从而实现低碳减排.二氧化碳的回收利用具有社会可持续发展,改善环境,提高经济效益等社会意义.%The source,characteristics and applications about CO2,a comparative analysis of CO2 recycling technology,and the principle and process characteristics of four various CO2 recovery technologies(the physical absorption,chemical absorption,adsorptive separation and membrane separation,and so on) were introduced.The source,application and economy analysis of CO2 showed that research emphasis of CO2 reclaim was reducing the use of fossil fuels and improving the recovery technology and comprehensive utilization of CO2.The CO2 recycling technology can have a lower carbon emission.The recovery and utilization of CO2 had the social significance of sustainable development,environmental improvement and economic benefits.
