Nickel catalysts supported on Al 2 O 3 , CeO 2  and ZrO 2  were prepared by wet impregnation method and evaluated in steam reforming of glycerol. The catalysts were characterized by chemical composition, textural analysis, crystalline structure and reducibility. The structural characterization of the catalysts revealed a good dispersion of Ni particles using the Al 2 O 3  support, needing higher reduction temperature. The reactions were performed at 500°C with 10 vol.% glycerol solution in a continuous flow reactor. All catalysts showed conversions close to 100%. The selectivity to gas products and formation of liquid by-products were found to be dependent on the type of support. The H 2  selectivity showed the following trend: ZrO 2  &gt; Al 2 O 3  ≈ CeO 2 . The catalyst supported on CeO 2  showed low activity for water-gas shift reaction, with the highest CO selectivity. All catalysts presented a low formation of CH 4 . In the liquid phase some by-products were identified (hydroxyacetone, acetic acid, lactic acid, acetaldehyde, acrolein and ethanol) and secondary reaction routes were proposed. Coke formation was higher on Ni/Al 2 O 3  catalyst, but no deactivation was observed during 8 h of reaction.
