Abstract: The effect of O2 content in the oxidative steam reforming (OSR) of raw bio-oil has been studied, and the kinetic behavior, particularly deactivation, has been compared between two catalysts (Ni/La2O3-αAl2O3 and Rh/CeO2-ZrO2). The experiments have been carried out in an apparatus with two steps in series: (1) thermal treatment (at 500 °C, for the controlled deposition of...
