摘要: 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.

摘要: In a process for the removal of siloxanes from biogas streams, especially a landfill gas stream or a gas stream from anaerobic digesters, the gas stream is first passed through a conventional siloxane removing unit to remove the majority of the siloxanes and subsequently passed over a selected catalyst with polishing effect, thereby removing remaining traces of siloxanes. The catalyst with polishing effect is chosen from i.a. zeolites, porous silica, titania and various metals on alumina or titania.
