摘要
Abstract
High capture cost is one of the major challenges restricting application of CCUS technology in low-carbon transformation of coal-fired power plants.Solid acid catalysts reduce energy consumption for CO2 desorption by lowering temperature,thereby reducing capture cost.This paper summarizes two mechanisms of promoting proton transfer and promoting deprotonation,as well as five types of solid acid catalysts including metal oxides/hydroxides/sulfates,molecular sieves,composite catalysts,organic framework materials,and activated carbon.Three catalyst preparation methods include precipitation,impregnation,and hydrothermal method.Effects of acidic sites,B/L acid ratio,basic sites,and mesoporous structure on desorption performance were revealed.Deficiencies of current research were pointed out,and future directions were proposed.Advantages and disadvantages of the performance of different types of catalysts were summarized to provide guidance for technology innovation and to promote industrial application of CCUS technology.关键词
