CARBON DIOXIDE SEPARATION VIA PARTIAL PRESSURE SWING CYCLIC CHEMICAL REACTION |
摘要 |
A method for separating a reactive gas from a feed gas mixture is disclosed. The method includes reacting the reactive gas with a bed of reactive solid in an exothermic reaction to create a second solid and a product gas from which the reactive gas is depleted. The product gas is removed and the heat from the reaction is used to liberate the reactive gas from the second solid in an endothermic reaction which yields the reactive solid. The reactive gas is removed and sequestered. Heat reservoir material is included in the bed to retain the heat in support of the endothermic reaction. A device for executing the method having an insulated chamber holding the bed, as well as process units formed of multiple beds are also disclosed. The process units allow the method to be operated cyclically, providing a continuous flow of feed gas, reactive gas and product gas. |
