    摘要: A method and device for treating a gas stream comprising at least one non-halogenated carbonaceous compound and optionally at least one halogenated organic compound. The gas stream, at 100.degree. C. to 650.degree. C. and in the presence of oxygen is contacted with a first catalyst in a first catalyst zone. The first catalyst comprises a first catalytic material deposited on a low acidity support material. In this zone, the non-halogenated compound is selectively reacted to form innocuous materials such as water and carbon monoxide. This can be followed by contacting the gas stream with a second catalyst in a second catalyst zone. The second catalyst comprises a second catalytic material deposited on a high acidity support material. In this zone, the halogenated organic compounds are reacted.
