A process for the removal of siloxanes from landfill gases

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 catal...

Zusammenfassung:	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.
