  • Catalyst system for enhanced flow syngas production
    Publication number: 20050181939
    Abstract: A method and apparatus for converting a hydrocarbon and oxygen containing gas feed stream to a product stream, such as syngas, including catalytically partially oxidizing the hydrocarbon feed stream over a catalyst bed. The catalyst bed has a downstream zone which is less resistant to flow than the upstream zone.
