摘要

吸附被认为是最有前途的CCS技术之一。气体吸附涉及使用固体吸附剂从烟气中分离气态组分。气态组分，即吸附物，是从气相吸附到固体材料上的。对于co2的吸附，重要的是考虑高吸附量、co2选择性、再生能力和多次循环稳定性等参数。提高吸附剂的吸附能力是吸附剂发展的新方向，为此，胺浸渍法应运而生。本文介绍了一种从粉煤灰中提取介孔材料的新方法，并在此基础上通过浸渍法制备了一种新型的物理化学吸附剂。热重分析和红外光谱分析证实了该工艺的有效性。

Optimization of Novel Sorbents for CO2Removal Based on FTIR and TG Analysis

Abstract Adsorption is considered as one of the most promising technologies for CCS. Gas adsorption involves the separation of gaseous components from flue gas using solid adsorbents. The gaseous component, adsorbate, is adsorbed from the gas phase on a solid material. Regarding CO2adsorption, it is important to consider the parameters, that is the high sorption capacity, CO2selectivity, regeneration and stability in multiple cycles. New directions for the development of adsorbents are focused on increasing their capacity - for this purpose, amine impregnation is carried out. This paper presents a new approach to obtaining mesoporous material from fly ash and, based on this, a new physico-chemical adsorbent obtained by impregnation. The effectiveness of the process was confirmed by thermogravimetric analysis and FTIR infrared spectroscopy.
