Patent ID: 7473402

Claim:
An ozone removal system for an aircraft, comprising: a housing having an upstream end and a downstream end; a substrate disposed within said housing, said substrate and said housing adapted for the passage of an air stream therethrough; a titania catalyst support disposed on a surface of said substrate; a first duct affixed to said upstream end of said housing, said first duct coupled to an air intake unit for providing said air stream; and a catalytic composition disposed on said titania catalyst support, said catalytic composition consisting of: a first catalytic component, wherein the first catalyst component is a silver-based component selected from the group consisting of Ag (silver) metal and AgO (silver oxide), and a second catalytic component, wherein the second catalyst component is a palladium-based component selected from the group consisting of PdO (palladium oxide) and PdO2 (palladium dioxide), wherein said catalytic composition is adapted for the catalytic removal of ozone from said air stream at temperatures within the range of from about 100 to 500° F.; and wherein the ozone removal system is resistant to poisoning by sulfur and phosphorus compounds.
