- Abstract
Post-combustion carbon dioxide (CO 2) capture via flue gas is an advanced technology for mitigating greenhouse gas emissions. Its significance lies in the potential for retrofitting this technology to the current inventory of coal-fired power plants. This review paper aims to present the state of art in the technologies of adsorption techniques in post-combustion technologies to capture CO 2 from flue gas streams. These techniques have demonstrated numerous potential benefits when compared to conventional CO 2 capture methods that utilize aqueous amine solvents. Additionally, this overview presents the development in the field of novel solid sorbents for post-combustion CO 2 capture, focusing on their enhanced performance and favorable economic feasibility. The promising potential of mesoporous silica has been recognized to evaluate the enhanced capacity of CO 2 adsorption offered by these materials. Several research studies have reported different techniques of functionalizing porous silica by introducing amine groups. Various methods of functionalization for mesoporous silica, such as impregnation, grafting, and hybrid approaches, have been examined to improve the efficiency of the sorbents. Furthermore, this work summarises the research challenges with porous silica materials and indicates the possibilities for future studies to improve post-combustion carbon.
