STABILIZED INORGANIC OXIDE SUPPORTS AND ADSORBENTS DERIVED THEREFROM FOR CARBON DIOXIDE CAPTURE

摘要

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.
