In this work, we investigated glycerol reaction order and activation energy to obtain several kinetic parameters in glycerol steam reforming reaction. Glycerol steam reforming for kinetics studies was carried out between 450 °C and 550 °C under atmospheric pressure with the glycerol concentration of 12-30 wt% in fixed-bed reactor. Kinetic parameters were obtained in the kinetically controlled reaction area. We also used the initial rate method to avoid effect on carbon deposition on surface of a catalyst. The glycerol reaction order and activation energy were calculated by power-law method and Arrhenius equation, respectively.
