摘要
大量化石燃料的燃烧造成二氧化碳等温室气体的过量排放,严重影响了全球的环境与气候变化。固体吸附剂由于易处理、能重复使用、原材料损耗小而受到二氧化碳捕集领域的广泛关注。主要针对近些年来发展起来的新型固体二氧化碳吸附剂优缺点进行了分析比较。根据其吸附温度的不同,分别以低温、中温和高温3类吸附剂进行分类讨论。重点讨论了高温固体钙基吸附剂的吸附性能,以及其常见的改性方法,由于其吸附量高、原材料丰富、成本低等优点,氧化钙基吸附剂被认为是最理想的高温吸附剂。
Excessive emissions of greenhouse gases such as carbon dioxide, have caused serious impact on climate and environment due to the combustion of fossil fuel. Solid adsorbents have attracted growing interests in fields of carbon dioxide capture technology owing to their unique advantages such as easy processing, re-usability, small loss of raw materials. In this paper, advantages and disadvantages of the solid sorbents, which have developed in recent years, are discussed. According to the difference of adsorption temperatures, the sorbents could be divided into three types： the low temperature, medium temperature, high temperature. This paper focuses on the adsorption properties and modification methods of high temperature calcium-based sorbents considering high temperature absorption of carbon dioxide. And calcium-based sorbents is the most ideal high-temperature adsorbent due to its high adsorption capacity, wide-distribution of raw materials and low costs.
