  • Method of separating carbon dioxide from carbon dioxide containing gas and combustion apparatus having function to separate carbon dioxide from the combustion gas
    Patent number: 5665319
    Abstract: A method of separating carbon dioxide from a carbon dioxide-containing gas is disclosed, wherein the carbon dioxide-containing gas is contacted with a metal oxide to fix the carbon dioxide as a metal carbonate, and the metal carbonate is thermally decomposed into metal oxide by contact with a combustion gas produced by combusting a fuel with a pure oxygen gas. The metal oxide thus produced is recycled to the previous step for fixation of carbon dioxide. A combustion apparatus is constructed to carry out the above method so that the combustion gas produced is treated to separate the carbon dioxide contained therein.
