The present disclosure relates to a process for capturing carbon-dioxide from a gas stream. In order to capture the carbon-dioxide, a support is provided and potassium carbonate (KCO) is impregnated thereon to form an adsorbent comprising potassium carbonate (KCO) impregnated support. The adsorbent is activated to form an activated adsorbent. The gas stream is passed through the adsorber to enable adsorption of the carbon-dioxide on the activated adsorbent to form a carbon-dioxide laden adsorbent. The carbon-dioxide laden adsorbent is transferred to a desorber for at least partially desorbing the carbon-dioxide from the carbon-dioxide laden adsorbent by passing a carbon-dioxide deficient stream through the desorber. The partially regenerated adsorbent is returned to the adsorber for adsorbing the carbon-dioxide from the carbon-dioxide. The process of the present disclosure reduces the overall energy demand by partially regenerating the adsorbent.

Process for capturing carbon-dioxide from a gas stream

The present disclosure provides a single compression system and a process for capturing carbon dioxide (CO) from a flue gas stream containing CO. The disclosure also provides a process for regeneration of the carbon dioxide capture media.

Single compression system and process for capturing carbon dioxide

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&#xb0; C. The carbon dioxide adsorption capacity of the regenerated support is between 70 and 90% of the theoretical carbon dioxide adsorption capacity.

Stabilized inorganic oxide supports and adsorbents derived therefrom for carbon dioxide capture

The present disclosure provides a multiple-compression system and a process for capturing carbon dioxide (CO) from a flue gas stream containing CO. The disclosure also provides a process for regeneration of the carbon dioxide capture media.
