| Sorbent-based CO2 capture technology is considered as one of the potential scientific techniques for mitigating greenhouse gas emission. Major advantages of sorbent based adsorption are its low regeneration energy coupled with the elimination of corrosion and equipment degradation characteristic of amine based solvent CO2 capture systems which are the preferred industrial methods.;Different CO2 capture configurations, processes, and operational parameters for different sorbents were reviewed and summarized. Efficient industrial applications for CO2 capture require that solid sorbents possess an adsorption capacity between 1000-2000micromol/g or more together with a long-term regeneration capacity. Economical consideration necessitates that the cost of CO2 sequestration be less than ;Huang reported that MCM-48 silica grafted with 3-aminopropyltriethoxysilane had the greatest CO2 adsorption capacity under anhydrous conditions with 2.30mmol/g sorbent. While Harlick reported that TRI-PE-MCM-41 had the greatest CO2 adsorption capacity under wet conditions with 2.94mmol/g sorbent. |
