  • Patent number: 5186859
    Abstract: Catalytic partial oxidation process for converting natural gas to synthesis gas in which the process operates at high temperature T>1000.degree. C. with entrained catalyst. Fine catalyst particles are transferred by means of a gas stream to a burner device which effects a rapid and intensive mixing of this gas stream with the reactants, e.g., natural gas, oxygen and steam. The catalyst entrained by the product gas stream is separated from this stream and recycled to the reactor.
