The kinetic study of the oxidative dehydrodimerization of propylene over the Bi-Ce oxide catalyst showed that the dimer formation reaction is first order with respect to the partial pressure of propylene and is zero order with respect to that of oxygen, while the formation of carbon dioxide is zeroth order and 0.35 order with respect to the partial pressure of propylene and to that of oxygen, respectively. It is considered that the dimerization and the complete oxidation of propylene take place on different active sites patallelly and the coupling of propylene is the rate-determining step, which is a result of the reaction between a gaseous propylene molecule and an adsorbed one on the catalyst surface (Eley-Ridsal type).
