摘要： A reaction-based process has been developed for the selective removal of carbon dioxide (CO 2 ) from a multicomponent gas mixture to provide a gaseous stream depleted in CO 2 compared to the inlet CO 2 concentration in the stream. The proposed process effects the separation of CO 2 from a mixture of gases (such as flue gas/fuel gas) by its reaction with metal oxides (such as calcium oxide). The Calcium based Reaction Separation for CO 2 (CaRS-CO 2 ) process consists of contacting a CO 2 laden gas with calcium oxide (CaO) in a reactor such that CaO captures the CO 2 by the formation of calcium carbonate (CaCOa). Once "spent", CaCO 3 is regenerated by its calcination leading to the formation of fresh CaO sorbent and the evolution of a concentrated stream of CO 2 . The "regenerated" CaO is then recycled for the further capture of more CO 2 . This carbonation-calcination cycle forms the basis of the CaRS-CO 2 process. This process also identifies the application of a mesoporous CaCO 3 structure, developed by a process detailed elsewhere, 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.

The proposed process effects the separation of CO 2 from a mixture of gases (such as flue gas/fuel gas) by its reaction with metal oxides (such as calcium oxide). The Calcium based Reaction Separation for CO 2 (CaRS-CO 2 ) process consists of contacting a CO 2 laden gas with calcium oxide (CaO) in a reactor such that CaO captures the CO 2 by the formation of calcium carbonate (CaCOa). Once "spent", CaCO 3 is regenerated by its calcination leading to the formation of fresh CaO sorbent and the evolution of a concentrated stream of CO 2 . The "regenerated" CaO is then recycled for the further capture of more CO 2 . This carbonation-calcination cycle forms the basis of the CaRS-CO 2 process. This process also identifies the application of a mesoporous CaCO 3 structure, developed by a process detailed elsewhere, 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.
摘要翻译：已经开发了基于反应的方法，用于从多组分气体混合物中选择性去除二氧化碳（CO 2 SUB），以提供与入口CO 2相比贫CO 2的气体流。在流中的浓度。所提出的方法通过与金属氧化物（例如氧化钙）的反应从气体混合物（例如烟道气/燃料气体）中分离CO 2。基于钙的反应分离为CO _{2 （CARS-CO _{2 ）过程包括接触的CO _{2 与氧化钙含尘气体（CaO）的在反应器中使得CaO通过形成碳酸钙（CaCO 3）捕获CO 2。一旦“消耗”后，CaCO 3通过其煅烧而再生，导致新鲜CaO吸附剂的形成和CO 2浓缩物流的产生。然后再生“再生”的CaO以进一步捕获更多的CO _{2 。该碳酸化 - 煅烧循环形成CaRS-CO <2>过程的基础。该过程还确定了由其他地方详述的工艺开发的介孔CaCO 3 SUB结构的应用，其在多次碳化和煅烧循环中获得> 90％的转化率。最后，真空下的热再生（煅烧）提供了更好的吸附剂结构，其在多个循环中保持可再现的反应性水平。}}}}
