| Abstract: | SmFeO_3 was prepared by the complexation method of citric acid.The perovskite structure of SmFeO_3 was determinated by XRD. The Redox mechanism for the oxidation of CO was proven by the pulse method of reduction with CO and reoxidation with O_2 over SmFeO_3 catalyst.The steady-state kinetics of oxidation for CO over SmFeO_3 has been investigated with an external circulation flow reactor.The parameters of Redox equation were estimated by the method of orthogonol design. The kinetic equation of the reduction stage obeys the Bassett-Habgood equation of pulse method. |
