Patent ID: 8795588

Claim:
A method for removing volatile organic compounds from an air stream, the method comprising: passing an air stream through first adsorbent device comprising an adsorbent material to remove deactivating agents capable of deactivating a catalyst of the type used to remove contaminants from the air stream by forming chemical bonds with the deactivating agents, wherein the deactivating agents are selected from the group consisting of siloxanes, silanes, other silicon containing volatile or semi-volatile compounds, nitrogen containing volatile or semi-volatile compounds, phosphorus containing volatile or semi-volatile compounds, sulfur containing volatile or semi-volatile compounds, and any combination thereof; adding water to the air stream to chemically bind the adsorbent material and the catalyst deactivating agents; and passing the air through a catalytic reactor located downstream, with respect to a direction of the air stream, of the adsorbent device to remove contaminants from the air stream.
