  • Process for producing hydrogen from hydrogen sulphide in a gas fluidized bed reactor
    Patent number: 4439412
    Abstract: The present invention relates to a method of catalytic and thermochemical decomposition of hydrogen sulfide gas. A metal chemical catalyst, preferably comprised particularly of iron and other transition metals is employed in a gas fluidized bed reactor in which a substantially constant temperature is maintained to crack the hydrogen sulfide. The sulfur is bound chemically to the chemical catalyst and the hydrogen is sent to a transportation system for recovery. The chemical catalyst can be regenerated by raising the temperature in the gas fluidized bed.
