Lavrentieva, 5, Novosibirsk, Russia3 Biomass Technology Group B.V., Josink Esweg 34, Enschede, The NetherlandsLignocellulosic biomass can be converted efficiently via fast-pyrolysis intopyrolysis oil, an attractive liquid energy carrier [1]. However, the application ofpyrolysis oil (e.g. as feedstock for existing refinery units) is limited due to its limitedthermal stability, high acidity, and high viscosity. To enhance the application range ofpyrolysis oil, catalytic hydrotreating of the pyrolysis oil has been proposed [2]. Themajor objectives of catalytic hydrotreating are a reduction of the oxygen content, andto achieve a product with improved stability and lower viscosity. Here we report ourstudies on catalytic hydrotreatment of pyrolysis oil using NiCu/δ-Al 2 O 3 catalysts with arange of Ni/Cu ratios in a batch set-up. Good deoxygenation levels were observed,though distinct differences in the perfomance were present (Figure 1).This study clearlyindicates that NiCu/δ-Al 2 O 3catalysts have high potentialfor the catalytic upgrading ofpyrolysis oils.
