Patent ID: 7896951

Claim:
A system for reducing carbon dioxide emissions from gasses generated in burning fossil fuel, comprising: a vessel configured (i) to direct gasses generated in burning fossil fuel, in an upwardly flow at a velocity from a lower portion of the vessel to an upper portion of the vessel, (ii) to receive, into the upper portion of the vessel, first type solid particles capable of absorbing heat from the gasses and second type solid particles capable of capturing carbon dioxide from the gasses, and (iii) to direct the received first type solid particles in a downwardly flow from the upper portion of the vessel to the lower portion of the vessel, wherein the velocity of the upwardly flow of gasses (i) is sufficient to cause the second type solid particles to flow with the upwardly flowing gasses to a first vessel discharge and (ii) is insufficient to impede the downwardly flow of the first type solid particles to a second vessel discharge; a separator configured (i) to separate the second type solid particles with captured carbon dioxide from the gasses discharged from the first vessel discharge, and (ii) to direct the separated second type solid particles with the captured carbon dioxide to a separator discharge; and a reheater configured (i) to direct the first type solid particles with absorbed heat discharged from the second vessel discharge and the second type solid particles with the captured carbon dioxide discharged from the separator discharge in a downwardly flow to a first reheater discharge, such that heat from the first type solid particles causes the captured carbon dioxide to be released from the second type solid particles, and (ii) to direct the released carbon dioxide to a second reheater discharge.
