Abstract
A method is disclosed for removing ozone from a gas. According to this method, the gas is contacted with an adsorbent that includes a transition metal oxide or metal organic framework to form a treated gas. The treated gas is contacted with a noble metal catalyst to catalytically decompose ozone in the treated gas, thereby forming an ozone-depleted treated gas.
Claims8
A method of removing ozone from a gas, comprising:
- contacting the gas with an adsorbent comprising a metal organic framework to form a treated gas;
- contacting the treated gas with a noble metal catalyst and catalytically decomposing ozone in the treated gas at a temperature of 50-350° C. to form an ozone-depleted treated gas;
- and
- applying heat to the adsorbent from a heat source to regenerate the adsorbent.
