Definitions

  • the invention relates to a reformer having a first media feed area to which fuel and oxidant can be supplied, an oxidation zone adjoining the first media feed area in which the media fed to the first media feed area react at least partially to flue gas, a second media feed area to which at least fuel can be fed , a mixture forming zone, which connects to the oxidation zone and the second RulezuSIC Scheme and in which a fuel-flue gas mixture can be generated, and a subsequent to the mixture formation zone reforming zone, in which the fuel-flue gas mixture is catalytically reformable.
  • Such reformers are used to produce from hydrocarbons, such as natural gas, gasoline or diesel, a hydrogen-rich reformate, which can be supplied to the production of e- lectric energy of the anode side of a fuel cell.

  • the flue gas Before the occurrence of the resulting in the oxidation of the flue gas into the catalyst, the flue gas is mixed with more fuel, so that the reforming zone to be supplied fuel-flue gas mixture is available.

  • the total air ratio should be in the range of 0.4. In order to further influence the air ratio, provision can also be made for a further oxidant supply to be provided in the second media feed region.
  • the invention has the object of developing a reformer in such a way that an undesirable auto-ignition is prevented in a mixture formation zone in a simple manner.
