BA5206 Gasification and synthesis gas processing

Research output: Patent › Patent

Abstract

The invention relates to a method and an apparatus for purifying gas, wherein the gas which includes at least tars and/or undesired hydrocarbons is supplied to a catalytic treatment reactor which has at least one catalyst zone including at least one catalyst element with a catalyst, oxygen gas is fed into the catalyst element of the catalyst zone in the catalytic treatment reactor and is supplied through the catalyst element, the gas is arranged to flow to the catalyst zone and arranged to contact with the oxygen gas and the catalyst, and a purified gas is discharged from the catalytic treatment reactor. Further, the invention relates to the use of the method.
