STUDY ON CAPTURE, RECOVERY AND UTILIZATION OF CARBON DIOXIDE

摘要

For the low concentration CO_2 exhaust gas from coal-fired power plant, steel plant emission trapping and recycle problem, a pressure swing adsorption process was studied, using a porous imidazolate framework materials (ZIFs) as adsorbent, separating carbon dioxide from fuel gas mixture. In the carbon dioxide reduction condition by electrochemical method, using ionic liquids as electrolyte, the oxygen and carbon products could be obtained, including carbon nanotube, nano carbon fiber and amorphous carbon. At last, a new CO_2 collection, recycling and reuse technology was formed.
