Research Progress on Carbon Dioxide Capture Pathways and Technologies under Carbon Neutrality Targets
To actively address global climate change and fulfill the commitments of"carbon peak"and"carbon neutrality,"it is essential to minimize greenhouse gas emissions.Carbon dioxide capture is a primary means of reducing greenhouse gas emissions and achieving carbon neutrality.Based on the different timing of carbon sepa-ration from fuels,carbon dioxide capture pathways can be categorized into pre-combustion capture,post-com-bustion capture,and air capture;the main capture technologies include chemical absorption,physical adsorption,membrane separation,and low-temperature condensation.This paper analyzes the classification,principles,ad-vantages,disadvantages,current industrial applications,and existing issues of the latest carbon dioxide capture pathways and technologies at home and abroad.It also prospects the research directions for improving the industri-al application level of carbon dioxide capture technologies,pointing out that efficient absorption and desorption technologies,carbon dioxide adsorption kinetics,high permeability and selectivity with low pressure drop carbon dioxide separation membrane components,and condensation coupling technologies are key areas for future re-search.
