Comparative Tests of Catalysts for Reforming of Tars and Methane in Biomass-Derived Synthesis Gas from Fluidized Bed Gasification

C. Hamel, H. Lohmann, T. Schulzke & C. Unger
Several different commercially¬available and recently¬developed catalysts were tested for the reforming of model tar compounds and methane in a simulated producer gas from allothermal biomass gasification in a laboratory scale test rig at Fraunhofer UMSICHT. Monolith and bulk catalysts were compared with respect to their conversion performance in a synthetic syngas in a first project step without typical poisoning substances like e.g. sulfur. Precious¬ metal catalysts were able to almost completely remove aromatic compounds even...
