Zeolite regeneration is performed by first depressurizing the zeolite bed, which allows the adsorbed gases, such as nitrogen, to desorb from the pores. In some cases, a flow of dry air or inert gas may be used to purge the zeolite bed of any remaining nitrogen. Additionally, heat may be applied to remove moisture or other impurities that could reduce the adsorption efficiency. This heating process is more common in industrial setups where zeolite is exposed to contaminants.
