指出了CO2浓度与温室效应之间的关系，CO2捕集是有效的解决方案之一。常用的捕集方法有：溶剂吸收法、富氧燃烧法、空气捕集、膜分离法、变压吸附（PS A ）法等。分析比较了各种捕集方法的优缺点：溶剂吸收法吸收剂易被分解且再生能耗高，对设备腐蚀大；富氧燃烧法在制备氧气时能耗高，只能去除可燃性杂质；从空气中捕集CO2，浓度较低空气洗涤器规格过大，焙烧CaCO3时能耗高；膜分离法对原料气的要求较高；变压吸附法需要2次加压，能耗高，运行成本大。提出了CO2捕集技术的发展方向与建议。

This article reveals the relationship between the concentration of CO 2 and air temperature ,and points out that carbon dioxide capture and storage is one of the effective solutions .The commonly used methods of CO2 capture include solvent absorption ,oxygen -rich combustion ,capturing CO2 from ambient air ,membrane separation and pressure swing adsorption ,etc .The article makes a comparative analysis of advantages and disadvantages of these capture methods .The results show that the absorbent is easily decomposed and the equipment is corroded by the alkaline absorbent ;the method of oxygen - rich combustion can only remove combustible impurities , and the operating costs during the preparation of oxygen are expensive ;in the process of roasting calcium carbonate need high energy efficiency ,and the air scrubbers are very large ;raw gas of membrane separation has highly purity ;pressure swing adsorption needs high pressure ,energy consumption and operating costs .At last ,the article presents the development direction of carbon dioxide capture technology .
