Abstract
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 COfrom a mixture of gases by its reaction with metal oxides. The Calcium based Reaction Separation for COprocess consists of contacting a COladen gas with calcium oxide in a reactor such that CaO captures the COby the formation of calcium carbonate. Once 'spent', CaCOis regenerated by its calcination leading to the formation of fresh CaO sorbent. The 'regenerated' CaO is then recycled for the further capture of more CO. This process also identifies the application of a mesoporous CaCOstructure, 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.
