In the context of global carbon emissions and greenhouse effect,Carbon capture,Utilization and Storage(CCUS)technology is developing rapidly.Among these,the post-combustion carbon capture technology represented by pressure swing adsorption(PSA)technology has attracted much attention due to its huge market potential.However,the efficiency and cost-effectiveness of its adsorption capabilities require further optimisation.This paper introduces the background of global carbon emissions and the basic technology features of CCUS,with a focus on analyzing the research progress of pressure swing adsorption technology.The paper starts with the working principle and the regeneration process of PSA technology.Then the performance characteristics and research progress of adsorption materials represented by silica gel and activated carbon are summarized.Finally,various pressure swing adsorption technologies represented by low-pressure pressure swing adsorption technology are reviewed.The process flow and application progress of the process were analyzed,and its technical and economic analysis was conducted.The study identifies critical factors affecting the adsorption efficiency of materials,suggesting that enhancements in the efficiency of adsorbents can be achieved through alterations in their structure,manufacturing,and functional properties.Low-pressure pressure swing adsorption technology,recognized for its simple process flow and significant economic benefits,emerges as an important approach to achieve industrial carbon capture.Based on the above,research prospects are put forward to address the existing shortcomings,thereby providing a reference for the development of adsorption materials and improvement of adsorption processes.
