摘要
温室气体CO2 排放量巨大是导致全球气候变暖的主要原因之一,CO2 捕集、利用与封存(CCUS)技术是未来化石燃料大规模利用中实现CO2 近零排放的唯一路径.综述了燃烧前CO2 捕集、燃烧后烟气中CO2 捕集、燃烧中CO2 捕集(富氧燃烧和化学链燃烧)技术的研究与应用现状,总结了吸收法、吸附法、膜分离法等CO2 分离技术的研究进展,并指出:未来在积极开发高效、节能CO2 捕集技术的同时,应着重提高CO2 气体高值利用技术的研究力度,以降低CCUS的成本.
Abstract
The huge emission of greenhouse gas CO2 is one of the main reasons for global warming.CO2 capture,utilization and storage(CCUS)technology is the only way to achieve near zero CO2 emissions in the large-scale utilization of fossil fuels in the future.The research and application status of carbon dioxide capture before combustion,post-combustion carbon dioxide capture of flue gas and carbon dioxide capture technologies during combustion(oxygen enriched combustion and chemical looping combustion)was elaborated.The research progress on CO2 separation technologies such as absorption,adsorption and membrane separation was also summarized.And it was pointed out that the focus in the future should be on enhancing the research on high-value CO2 gas utilization technologies to reduce the high cost of CCUS,while actively developing efficient and energy-saving CO2 capture technologies.
