(WO9622941-A1)      The prodn. of a gaseous mixt. comprising 5-20 vol.% H2 and 80-95 vol.% methane comprises oxidn. of methane with water vapour at 400-500C and pressure 1-5 atmos. in the presence of a catalyst comprising Pd or binary alloy of Pd with a metal of Gp.IB, IIA, VIII and the lanthanides, supported on a porous carrier.    The oxidn. is at atmos. pressure and temp. 400-450C. The catalyst is Pd, Pd-Ni, Pd-Cu, Pd-Mg, Pd-La or Pd-Ce. The carrier is alumina, silica or zirconia, pref. -alumina. The catalyst contains 2 wt.% Pd or 1:1 wt. ratio alloy. The oxidn. is carried out at methane/water feed ratio 2.5, pref. 3.5, dry gas feed rate 20-100, pref. 25 ml/min., and mass supported catalyst of 0.2-1, pref. 0.2g. The amt. of inert porous material is 1-2 times amt. of supported catalyst.    USE -   For prodn. of a gaseous mixt. of hydrogen and methane (hythane), useful as alternative fuel for internal combustion engines.    ADVANTAGE -   Provides economical prod. of hythane under low temp. and pressure, at or near vehicle fuelling sites, thus eliminating the storage and transportation of reactive hydrogen.
