More Information
Summary:The present invention relates to a stabilized inorganic oxide support for capturing carbon dioxide from gases having high regeneration capacities over many cycles. The method for preparing the stabilized inorganic oxide support includes stabilizing an alumina-containing precursor by either calcining or steaming, impregnating an alkali or alkaline earth compound into the stabilized alumina-and drying the alkali or alkaline earth compound-impregnated stabilized alumina. The stabilized inorganic oxide support can be regenerated at lower temperatures between 100 and 150° C. The carbon dioxide adsorption capacity of the regenerated support is between 70 and 90% of the theoretical carbon dioxide adsorption capacity.
