A synthesis gas (syngas) with a composition corresponding to that of a biomass gasifier has been reformed over Rh-containing monolith catalysts in the absence and presence of typical undesired species in the syngas. When toluene, a typical light tar component, was added, there was some loss of conversion, probably due to competitive adsorption and reaction with toluene, although dealkylation of toluene can not be ruled out. Significant deactivation due to the tar was not detected. Potassium components impregnated onto the catalyst (KNO3 and KCl) in low concentrations gave slight enhancement of the reforming rates, but at higher concentrations there was severe deactivation.
