Title:
COMBINED HYDROCARBON/OZONE CONVERTER FOR AIRPLANE BLEED AIR SYSTEM
Document Type and Number:
WIPO Patent Application WO2005000467
Kind Code:
A8
Abstract:
The present invention provides a method and system for combined conversion of ozone and organic compounds in airplane bleed air. Catalytic converters have previously been used to reduce the levels of ozone in airplane bleed air. However, these converters have not yet provided an efficient system and method for effectively and simultaneously removing both ozone organic compounds (including hydrocarbons). The present invention accomplishes the goals of removing both harmful substances by providing a washcoat on a single anodized surface layer, wherein the washcoat may contain an active metal oxide which is active for ozone conversion may be impregnated with an active metal which is active for hydrocarbon and carbon monoxide conversion. Thus, a signal system is disclosed that destroys both ozone and hydrocarbons.
