<P>PROBLEM TO BE SOLVED: To provide a method and a system for separation of carbon dioxide which have a system arrangement with excellent energy efficiency and employ a lithium compound oxide. <P>SOLUTION: A method of separating carbon dioxide has an absorption process of incorporating, as an absorption material, a lithium composite oxide into an apparatus behaving as a carbon dioxide release source to make the oxide absorb carbon dioxide in the gas and a release process of causing the absorption material to release carbon dioxide in a regeneration unit. The operating conditions of the system are set so that the removal rate of carbon dioxide in the gas is 20-40%. <P>COPYRIGHT: (C)2007,JPO&INPIT |
