摘要

为进一步降低碳捕集技术成本,提高CO2 解吸效率,制备了一种低成本的金属改性凹凸棒土(ATP)固体酸催化剂,通过调控催化剂酸位丰度促进胺溶剂再生速率.结果表明,ATP-Zr可将CO2 解吸量和解吸速率分别提升13.8%和42%.此外,对合成的催化剂进行了表征分析以及成型工艺的研究,可为固体酸催化剂制备及低能耗CO2 捕集技术的工业化应用提供理论支撑.

Abstract

To further reduce the cost of carbon capture technology and improve CO2 desorption efficiency,a low-cost metal modified attapulgite(ATP)solid acid catalyst was prepared.The rich acid sites of the catalysts promoted the regeneration of amine solvent.The result showed that the introduction of ATP-Zr in-creased the amount and rate of CO2 desorption by 13.8%and 42%respectively.The catalyst was also characterized and investigated for the forming process.This work can serve as a reference for the prepara-tion of SACs and the industrial application of energy-efficient CO2 capture technology.
