To diversify energy sources and to address the impacts of global warming, the transformation of biomass, a renewable energy source, into fuels and chemicals is becoming increasingly necessary. The gasification technology is an efficient way of converting biomass via syngas into sustainable fuels. By‐products, especially tar, are formed during the gasification process and need to be removed before further downstream processing. Mo/V/W‐mixed oxides were found to be applicable for the catalytic tar oxidation in CO/H 2 atmosphere by adding a stoichiometric amount of oxygen. In temperature‐programmed experiments the reactivity of different tar model compounds during the selective oxidation on Mo/V/W‐mixed oxides as well as the catalytic performances of V 2 O 5 , WO 3 , and MoO 3 during the tar oxidation were investigated.
