US Patent 7569203 Production and uses of carbon suboxides

Methods for the reduction of gaseous carbon dioxide emissions from combustion or oxidation reactions are provided. The various methods involve the formation of carbon suboxides and/or polymerized carbon suboxides (PCS), preferentially over gaseous carbon oxides to thereby reduce gaseous carbon dioxide emissions. The various methods can be employed for efficient generation of energy and/or hydrogen. In addition, various methods for the use of polymerized carbon suboxide are disclosed.
