Steady-state kinetics and osillation phenomena for complete oxidation of benzene over Pt/Al2O3 catalyst

The steady-state kinetics for complete oxidation of benzene over Pt/Al2O3 has been investigated by the external recycling reactor. The kinetics equation was described by the L-H model of adsorption of benzene and oxygen with the inhibition of carbon dioxide. The parameters of the kinetics model were estimated by the method of orthogonal design. The heats of adsorption of benzene, oxygen and carbon dioxide were determined by the method of gas-adsorption chromatography. The details of oscillations of complete oxidation of benzene were investigated.
