Abstract
In order to confirm the possibility to be a high temperature CO2 absorbent, a reversible reaction between lithium zirconate and CO2 was examined. Experimental results revealed that lithium zirconate powder absorbs 400 times as much CO2 in volume preferentially at around 500°C and under high CO2 partial pressure. Since the fuel reforming or shift conversion process in power plants is performed in a pressurized gas atmosphere at 400–700°C, the fact suggests the advantage of lithium zirconate as the absorbent in energy power plants.Keywords
