A process of producing hydrogen by autothermal steam reformation of a hydrocarbon comprises the steps of providing a reactor vessel having a fluidized catalyst bed, introducing steam and a gaseous hydrocarbon, introducing oxygen, maintaining the bed temperature below the spontaneous combustion temperature of the hydrocarbon in a fluidized bed, and withdrawing hydrogen by means of a perm selective membrane. An apparatus for producing hydrogen comprises a reactor vessel, steam and hydrocarbon inlets, an oxygen inlet, a fluidized bed of catalyst within the reactor vessel and a perm selective membrane for withdrawing hydrogen from the reactor.

[ What is claimed is:] [1.]1. An autothermal process for producing hydrogen comprising the steps of:a) providing a reaction vessel enclosing a fluidizable catalyst bed of a suitable particulate catalyst;b) fluidizing the catalyst bed by introducing reacting gases comprising a mixture of preheated steam and hydrocarbon gas into the catalyst bed such that the fluidized bed forms a reaction zone;c) introducing oxygen into the reaction zone;d) oxidizing a portion of the hydrocarbon gas in the reaction zone;e) reforming the hydrocarbon gas with the steam to produce hydrogen gas in the reaction zone; andf) separating and collecting the hydrogen gas by means of a perm selective membrane.
