Abstract: Experimental investigations into stationary thermochemical recuperation are presented with three modifications compared to current researches: (I) A recuperative reformer was used. Current waste heat regeneration concepts use regenerative heat exchangers, which have numerous disadvantages: size, leakage and unsteady operation. In contrast, recuperative reformers enable the possibility of compact design and allow stationary operation. (II) The energy available for the reforming process was provided with the thermal energy of exhaust gases. (III) Oxygen was added to the reforming reaction. In the experiments, exhaust gases were used as reactants. The reactants are thus characterized by a fixed molar ratio of H2O/CO2=2/1 causing a maximum steam-to-carbon-ratio of 0.5. Steam-to-carbon-ratios of this size favour coke formation. The addition of oxygen to the reactants caused partial oxidation of methane which additionally released steam and increased the reaction temperature. Coke formation was thus inhibited.
