Gaseous products from reaction of CH4 and Fe oxide with enough hydrocarbons to react with the CO2 and or Ni, at elevated temperature and pressure.  The metal oxide is kept in a fluidized state.  A pressure head for the parts of the process to be conducted under pressure is achieved by locating the vessel for the oxidation of the metal at a considerably higher lever than the other vessels and connecting the former with the latter by a standpipe in which the metal oxide is kept in a fluidized state.  The exothermic heat in the oxidation stage is carried directly into the reduction and reforming stages by a heat carrier.  The carrier may be the metal used in the process in its free state.  The period of contact for hydrocarbon and metal oxide is relatively long before the mixture enters the reforming stage.  This lowers the C formation.  The metal oxide may be on a light carrier such as MgO or Al2O3.
