Capturing CO2 from point sources of emission, like power plants or cement manufacturing facilities, can help slow catastrophic global warming. We will develop a fluidized bed reactor system for point source capture of CO2, using powdered or porous granular calcium carbonate as the single-ingredient solid adsorbent via the CaCO3 + CO2 + H2O ↔ Ca(HCO3)2 cycle.
