The chemical kinetics of the steam reforming of the pyrolysis oil of polypropylene (PP) over a ruthenium-based catalyst has been examined as a function of pyrolysis oil and steam partial pressures at various temperatures. The activation energy of steam reforming over Ru/Al2O3 catalyst is 136 kJ/mol, and the reaction orders of pyrolysis oil and steam are 0.42 and 0.24, respectively. Fitting the experimental data to the Langmuir?Hinshelwood expression shows that the steamreforming reaction probably proceeds via the dissociative adsorption of pyrolysis oil and steam on two different sites.
