The oxidation of CO with oxygen over a Pt/γ-alumina catalyst is proposed as a model reaction to be used for the determination of mass transfer coefficients in packed and fluidized beds. It is applicable at relatively low temperatures (<800 K) and for very small particles (<100 μm). In the present work, the kinetics of this reaction have been verified in a small fixed bed facility (average particle diameter 54 μm), for various reactant concentrations, temperatures and superficial gas velocities. As a result, Langmuir–Hinshelwood kinetics (Ea=75.4 kJ mol-1) appeared to describe the experimental results better than a power law expression (Ea=90.6 kJ mol-1). Three temperature regimes can be identified upon interpretation of experimental results...
