摘要随着科学技术的不断发展,现在的人们社会生活日益丰富,可是,伴随着各种能源在各个领域的利用,全球变暖已经渐渐走进我们的身边,对于二氧化碳的控制与减排也更加迫切。很多国家都在寻找减少二氧化碳排放的措施,研究其捕集和封存的技术,希望在排放的各个环节都能产生比较理想的减排控制效果,许多的研究方法也因此而产生。其中碱金属基吸收剂干法脱碳技术由于其独特的优点受到了广泛的关注。为进一步提高碱金属基吸收剂的脱碳能力,本文从钠基吸收剂入手,运用溶胶凝胶法制备吸收剂，以氨基进行修饰,并研究不同干燥法（包含常规干燥、超临界干燥和溶剂置换干燥）干燥后吸收剂脱碳性能的影响。其他的方法包括BET,SEM等用于进一步理解其动力学特性。27226

Title Effects of different drying methods on CO2 sorption performance of amine modified sodium-based sorbent
Abstract
With the continuous development of science and technology, people’s social life are increasingly rich, however, accompanied by a variety of energy used in various fields, global warming has become a fact thus how to reduce carbon dioxide emissions are also on the agenda. Many countries are seeking measures to reduce carbon dioxide emissions and study the CO2 capture and storage technologies. There are many kinds of CO2 capture technologies, and using alkali-based sorbent for CO2 capture is one of the hot spot researches due to that there are many advantages. In order to further increase the CO2 sorption capacity of the alkali-based sorbent, we started from Na-based sorbent and modified the sorbent with amine by using Sol-Gel method, and invistigted the effect of drying methods (including conventional method, Supercritical drying method and Solvent substitution method) on the CO2 sorption performance. Other method including BET, SEM and so on were used for further understanding the kinetic.
Keywords: carbon dioxide capture; alkali metal base; sol-gel method; Supercritical drying method
