Improving CO₂ desorption performance in monoethanolamine solutions by adding titanium pyrophosphate catalyst.

ABSTRACT: Catalytic CO₂ desorption has emerged as a crucial strategy for enhancing the efficiency of CO₂ capture and reducing energy requirements, thereby advancing chemical absorption methods. This study examines the catalytic effectiveness of titanium pyrophosphate (TiP₂O₇) in improving monoethanolamine (MEA)-based CO₂ absorption and desorption processes, comparing its performance with other titanium-based catalysts, including titanium dioxide (TiO₂), titanium tetrahydroxide (TiO(OH)₂), and titanium carbide (TiC). In TiP₂O₇, Ti ions function as Lewis acid sites by accepting electron pairs (LASs), P₂O₇^4- anions act as proton carriers, facilitating rapid proton transfer
