摘要:

人类活动导致的CO2过量排放,是造成全球气候变暖的主要原因,因此亟需一种能够有效控制CO2浓度增长的方法。直接空气捕获技术是目前唯一能够大规模实现碳排放负增长的技术。固体胺吸附剂,特别是硅载体固体胺吸附剂,因其具有高吸附能力、抗腐蚀、低能耗等优点,被广泛研究并用于环境空气中捕获CO2。将硅基固体胺吸附剂按照负载方式进行分类,并归纳了不同硅基载体对吸附剂性能的影响;提出粉末状固体胺吸附剂在工业应用中遇到的难题,整理并分析了固体胺吸附剂当前的成型方法;指出了开发高吸附量、高稳定性的成型固体胺吸附剂是CO2吸附剂工业化的未来趋势。

Abstract:

Excessive CO2 emission caused by a large number of human activities is the main cause of global warming,so a method to effectively control the increase in CO2 concentration is urgently needed.Currently,direct air capture is the only technology capable of achieving negative growth of carbon emissions on a large scale.Solid amine adsorbents,especially silicon?based ones, have been widely studied and used to capture CO2 from ambient air due to their advantages of high adsorption capacity,corrosion resistance,and low energy consumption.In this paper,silicon?based solid amine adsorbents were classified according to the mode of loading,and the influence of different silicon?based supports on the adsorbent performance was summarized.At the same time,the problems encountered in the industrial application of powdered solid amine adsorbents were put forward,and the current forming methods of solid amine adsorbents were sorted out.Finally,it is pointed out that the development of formed solid amine adsorbents with high adsorption capacity and high stability is the future trend of CO2 adsorbent industrialization.
