Abstract

Carbon dioxide utilization is an excellent strategy to control the rising concentration of carbon dioxide in the atmosphere. Its success relies on the effectiveness of carbon dioxide capturing and separation from emission points. Coal and natural gas-firing thermal power plants are the major causes of carbon dioxide emissions. This emphasizes the importance of techniques that effectively capture carbon dioxide from thermal power plants. Following capture, the separation of carbon dioxide from the flue gas mixture is also important to achieve ultrapure carbon dioxide suitable for chemical synthesis. Therefore, this minireview presents the techniques available for carbon dioxide capturing and separation. Also, the utilization methods of carbon dioxide are briefly outlined along with their merits and demerits. Special emphasis is given to the role of biochar materials in separating carbon dioxide from flue gas. We believe that this review will give an overview of carbon dioxide capturing, separation, and utilization methods.
