Abstract

Steam reforming of acetic acid as a model oxygenate present in bio-oil over Pt/ZrO2 catalysts has been studied. Pt/ZrO2 catalysts are very active, completely converting acetic acid and give hydrogen yield close to thermodynamic equilibrium. The catalyst deactivated by formation of oligomers, which block the active sites for steam reforming. The mechanism of both the reaction and deactivation was studied with kinetic and IR spectroscopic measurements on Pt/ZrO2 and ZrO2. Platinum was essential for steam reforming to proceed. ZrO2 had a role to activate steam. Mesityl oxide was a typical condensation product that could be formed from acetic acid on ZrO2 and this is a major precursor of oligomers. Steam reforming occurred at the Pt-ZrO2 boundary and that deactivation occurred when this boundary was blocked by oligomers. This is an abstract of a paper presented at the 228th ACS National Meeting (Philadelphia, PA, 8/22-26/2004).
