Research Abstract

Carbon dioxide was absorbed to form iron carbonate and replaced by hydrogen gas by the reaction with water and steel or scrap iron. The reaction conditions for an efficient process was studied. Pyrolysis behavior of the formed carbonate was examined, and the conversion of it to carbon monoxide and iron oxide was observed. An accompanying formation of organic molecules such as methane in the carbonation reaction indicates that the reaction can be used as a conversion process of carbon dioxide to carbon resource. A fuel cell could be powered by the hydrogen produced by the reaction.
