Assessment of Appropriate Geometry for Thermally Efficient CO2 Adsorption Beds

Carbon capture is one of the recently raised technologies to mitigate greenhouse gas emissions. Adsorption was introduced as an energy-efficient carbon process, and literature primarily shows utilization circular cross-sectional adsorption beds for this purpose. In regard, paper investigates different shapes adsorbent determine thermal uptake enhancements. Three geometries are considered: circular, square, triangular beds. Mg-MOF-74 used adsorbent, numerical simulation developed using a user-defined function coupled with ANSYS-Fluent. The results show that bed exhibits better capacity management compared other For example, 6 K less than during process. It recommended be temperature swing when pumping power not important. square comes second after lower pressure drop, suggesting such good candidates adsorption. could excellent choice compact CO2 both
