Reducing carbon dioxide (CO2) emissions from the burning of a fossil fuel

摘要

A system (10) for reducing carbon dioxide emissions from gasses generated in burning fossil fuel, includes a vessel (20), separator (38) and reheater (50). The upper portion (12) of the vessel (20) receives downward flowing, first type solid particles capable of absorbing heat from upward flowing gasses (22) and second type solid particles capable of capturing carbon dioxide from the gasses. The separator (38) separates the second type solid particles (26) with the captured carbon dioxide from the gasses discharged from the first vessel discharge, and directs the separated second type solid particles (26) with the captured carbon dioxide to a separator discharge. The reheater (28) directs the first type solid particles and the second type solid particles (24) with the captured carbon dioxide 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 (26).
