Abstract:
1. A method for carbon dioxide sequestration comprising the steps of: feeding carbon dioxide and a reductant into a combustion chamber, wherein the carbon dioxide and the reductant react in the combustion chamber, such that the reductant forms an oxide with oxygen from the carbon dioxide to form an oxidized reductant and the carbon dioxide is reduced to carbon; exhausting the oxidized reductant and the carbon from the combustion chamber; then, separating the oxidized reductant from the carbon; reducing the oxidized reductant to form reclaimed reductant; feeding the reclaimed reductant into the combustion chamber to provide the reductant for reducing the carbon dioxide; and wherein the step of separating the oxidized reductant from carbon further comprises the steps of: disposing in a vortex separator the oxidized reductant and the carbon exhausted from the combustion chamber; and separately removing the carbon and the oxidized reductant from the vortex separator in different flow lines.
