초록 ▼

A reaction-based process has been developed for the selective removal of carbon dioxide from a multicomponent gas mixture. The proposed process effects the separation of CO2 from a mixture of gases by its reaction with metal oxides. The Calcium based Reaction Separation for CO2 process consists of contacting a CO2 laden gas with calcium oxide in a reactor such that CaO captures the CO2 by the formation of calcium carbonate. Once "spent", CaCO3 is regenerated by its calcination leading to the formation of fresh CaO sorbent. The "regenerated" CaO is then recycled for the further capture of more CO2. This process also identifies the application of a mesoporous CaCO3 structure, that attains >90% conversion over multiple carbonation and calcination cycles. Lastly, thermal regeneration (calcination) under vacuum provided a better sorbent structure that maintained reproducible reactivity levels over multiple cycles.
