000149093 5203_ $$aAn environmentally friendly method of producing a hydrogen rich gas is the catalytic steam reforming of the aqueous fraction of pyrolysis liquids (bio-oil). For this purpose, the catalytic steam reforming process must first be improved, involving the
development of a catalyst appropriate for the process. In the present work, five different research catalysts have been prepared and tested. A Ni/AlMg catalyst was selected as a reference. Modifications to the catalyst were studied, incorporating Co or Cu by
coprecipitation or by incipient wetness impregnation. The experiments took place at 650 ºC and atmospheric pressure in a fixed bed and in a fluidized bed reactor, using an aqueous fraction (S/C = 7.6 mol H 2 O/mol C) of pine sawdust pyrolysis liquid. A spatial
time (W/m org) of 4 g catalyst min /g organics and an u/u mf ratio of 10 (in fluidized bed) were used. In both reactors, the incorporation of Co to the reference catalyst by coprecipitation improved its performance. No statistically significant differences were
found between the reference catalyst and its modification with Cu by coprecipitation. The modification of the catalyst by impregnation with either Co or Cu resulted in rapid catalyst deactivation. The catalyst deactivation rate was higher when the steam
reforming took place in the fixed bed reactor, although the initial H 2 and CO 2 yields were higher. In contrast, although the initial yields were lower due to the less effective gas-solid contact in the fluidized bed reactor, the stability of the catalysts was higher.
Furthermore, the difference between the performance of the coprecipitated cobalt modified catalyst and the other two coprecipitated catalysts was higher when the fixed bed reactor was used. Elemental analyses and TPO analyses of some of the catalysts
revealed a relationship between their stability and the quantity and characteristics of the coke deposited on their surface.
