摘要
温室气体中CO2的超量排放将导致全球温度上升及海平面上升等环境问题.目前,碳捕集利用与封存(CCUS)技术作为具有前景的策略引起了关注.介绍了 CCUS技术在燃烧前、燃烧中、燃烧后捕集CO2的研究现状及发展趋势.综述了燃烧后技术中的吸收法、吸附法、膜分离法、低温分离法、金属氧化物法、生物法、水合物法及混合捕集技术,比较CCUS各种方法的优缺点,对其进行可行性分析.
Abstract
Excess CO2 emissions from greenhouse gases lead to environmental problems,such as rising global temperatures and rising sea levels.Currently,as a promising strategy,carbon capture utilization and storage(CCUS)technology is attracting global attention.The study introduces the research status and development trend of CO2 capture technology by CCUS technology before,during and after combustion.The absorption method,adsorption method,membrane separation method,low temperature separation method,metal oxide method,biological method,hydrate method and mixed capture technology in post-combustion technology are summarized.By comparing the advantages and disadvantages of various methods in CCUS,the feasibility analysis of various capture methods is conducted.
