N2 - Steam reforming of acetic acid over Pt/ZrO2 catalysts was studied as a model reaction of steam reforming of biomass derived oxygenates. Pt/ZrO2 catalysts were very active; however, the catalyst deactivated in time by formation of oligomers which block the active sites for steam reforming. Temperature programmed oxidation of the used catalysts revealed that there are three types of deposits, on Pt, on ZrO2 close to Pt particles, and on ZrO2. The removal of the second type of deposit was essential to regenerate the catalysts. Thus, it was suggested that the Pt-ZrO2 boundary sites were active sites for steam reforming, where both Pt and ZrO2 participates in the reforming, to activate acetic acid and water, respectively. This is an abstract of a paper presented at the 231st ACS National Meeting (Atlanta, GA 3/26-30/2006).
