Patent ID: 7819947

Claim:
An adsorption process for the recovery of ozone from a feed gas mixture containing at least ozone and oxygen comprising (a) introducing the feed gas mixture into a first end of an adsorber vessel containing a zeolite adsorbent and selectively adsorbing ozone on the adsorbent; (b) withdrawing from a second end of the adsorber vessel a stream of oxygen essentially free of ozone; (c) terminating the flow of the feed gas mixture to the adsorber vessel, introducing a purge gas into the second end of the adsorber vessel, and withdrawing from the first end of the vessel an outlet gas mixture containing at least purge gas and desorbed ozone; and (d) introducing an additional component into the feed gas mixture or the feed gas mixture and the purge gas and adsorbing the additional component on the zeolite adsorbent, wherein the additional component when adsorbed reduces the decomposition of ozone that would occur in the absence of the additional component adsorbed on the zeolite adsorbent.
