Catalysts that contain platinum group metals (PGMs) are widely used in hydrocarbon processing, both for facilitating production processes, as well as for controlling/ abating harmful or unlawful exhaust emissions for end-of-pipe applications. Typical catalysts employed in petrochemical/ hydrocarbon processing applications incorporate PGMs, which are deposited on catalyst supports such as soluble or insoluble alumina, silica/ alumina or zeolites. At the exhaust end of a process, catalysts are also widely used for end-of-pipe control to reduce and/ or eliminate atmospheric emissions of volatile organic compounds (VOCs) and other pollutants generated by hydrocarbon processes.
