CO2 Capture Using Resin-Based Solid Amines: Characteristic, Application, Regeneration and Deactivation Mechanism

Abstract

The accumulation of CO₂ has been considered to be one of the main contributors to global warming and climate change, making carbon emission reduction and carbon capture technologies key research focuses. Out of the various technologies to lower atmospheric CO₂ levels, using solid amine adsorbents for CO₂ capture is seen as one of the most promising options. Porous resin materials are gradually being investigated as porous solid supports for amine functionalization due to their high specific surface area and high adsorption properties. In this review, we focus on the application of resin-based solid amines in carbon capture, offer a detailed overview of the synthesis methods for resin-based solid amines, and discuss how different supports and organic amines impact the performance of these adsorbent materials. We explore factors affecting the stability of these materials, including deactivation caused by heat, moisture, oxidation, CO₂, and impurity gases, to identify the causes and mechanisms of deactivation, and providing the thorough summary of how resin-based solid amines perform in CO₂ adsorption under various environmental conditions. Our review addresses a gap of resin supports in the current literature on solid amine adsorbents.
