| Abstract: | The kinetics of CO oxidation over new Pt/Al 2O 3 promoter is studied under the condition of regeneration of catalytic cracking. After eliminating the catalytic oxidation of reaction tube and diluent,the kinetics data are determined over the new promoter diluted to 10 -6 g/g.The reaction orders of carbon monoxide and oxygen are 1 and 0.5 when the oxygen is excessive.The reaction rate constant and its confidence region at 660℃ are also given herein. |
