摘要
二氧化碳是主要的温室气体之一,其大量排放已对全球的气候环境造成严重影响,迫切需要开发经济有效的二氧化碳捕集(简称碳捕集)技术。目前,碳捕集技术主要有吸收分离法、吸附分离法、膜分离法和低温分离法。首先,介绍了碳捕集技术的发展现状、应用研究进展和未来发展趋势;总结了国内外碳捕集示范项目;重点对比了各碳捕集技术的优势与缺点,同时强调了碳捕集技术面临的困难与挑战;指出目前主要的碳捕集技术均难以独立实现高效、节能、经济的碳捕集分离,需针对不同的应用场景,选择适合的分离技术,并提出了适用于分离场景的应用建议;最后简要介绍了混合捕集技术的研究成果,提出混合捕集技术可能是一种突破单一捕集技术瓶颈的可行方法。
Massive emission of carbon dioxide,one of the main greenhouse gases,has caused serious impact on global climate and environment,which led to urgent need of cost-effective separation and purification technologies for carbon dioxide capture.At present,separation technologies based on absorption,adsorption,membrane and low temperature are mainly adopted for carbon dioxide capture.In this review,the development status,application research progress and future directions of carbon capture technologies were discussed,followed by summarization on current post-combustion carbon capture projects at home and abroad especially the advantages,disadvantages and challenges of each existing carbon capture technology,which has difficulty in achieving efficient,energy-saving and economical carbon capture independently.It was then pointed out that separation technology should be chosen based on different application scenarios.In the end,the research achievements of hybrid capture technology was briefly introduced,which suggested that integration of different carbon capture technologies might lead to breakthrough of bottleneck in single capture technology.
