| 摘 要： | 温室气体CO2是当今世界环境恶化的主要原因之一,近年来针对CO2的捕集技术也相继被研究.磷石膏是湿法冶炼磷酸的副产物,具有产量大、微辐射性等特点,严重危害自然环境和人类健康.本文阐述二氧化碳捕集与封存(CCS)以及燃烧后捕集的三大方法的具体技术原理与特点,着重分析利用钙基吸收剂捕集CO2的技术特点和优势,提出CO2捕集技术的探索方向并指出利用磷石膏分解渣作钙基吸收剂矿化捕集CO2的思路.当前对CO2捕集的研究多停留在吸收剂捕集方面,单纯吸收剂虽吸收效果较好,但其成本较高.磷石膏分解渣作钙基吸收剂不仅有着良好的捕集效果,且解决了成本问题,实现了"以废制废"的思路.

| Abstract: | The greenhouse gas CO2 is one of the main causes of environmental degradation in the world. In recent years,CO2 capture technology has been on the spotlight. This article expounds the principle and characteristics of carbon dioxide capture and storage (CCS)technology,three methods of post-combustion capture of are summarized and compared. What's more,this paper mainly analyzes the characteristics and advantages by using calcium-based sorbent trapping CO2 ,puts forward the exploration direction of CO2 capture technology and points out the idea of using phosphogypsum decomposition slag as the calcium-based sorbent to mineralize CO2 in order to realize the purpose of "using waste to treat waste". |
