燃烧后CO2气体捕集技术研究

从燃煤电厂排出的烟气分离技术,分为即燃烧前处理、富氧燃烧以及燃烧后处理三类,阐述燃烧后的处理方法.这种方法有五大技术发展方向,包括吸收、吸附、膜分离、霜冻分离和生物捕捉.对这五个方向的技术做一些阐述,并列举这几个方向下正在开展的研究实例,对二氧化碳捕集技术做一个较全面的介绍.

Assessment of post-combustion carbon capture techmology development

The general conclusion for power plants to reduce or remove COn are three approaches： pre -com- bustion,post- combustion,and oxygen- fired combustion. The post- combustion carbon dioxide capture tech- nologies are discussed briefly. Current methods for post - combustion carbon dioxide capture include., liquid and dry absorption, adsorption, membrane separation, preparation by frosting, and biological fixation. The five carbon dioxide capture technologies are analyzed with a few examples for each of them,which gives a big picture,about the carbon dioxide capture technology.
