A Study on the Catalytic Oxidation Reaction of Carbon Monoxide with Nickel Oxide

NiO 촉매에 의한 CO 산화반응에 관한 연구
Jae Shi Choi, Keu Hong Kim

최재시, 김규홍
The catalytic reaction between carbon monoxide and oxygen was investigated with the various nickel oxide catalysts at different partial pressures of carbon monoxide and oxygen and at reaction temperatures in the region of 120°to 250℃. The reaction has the highest rate with the nickel oxide catalyst which is sintered at low temperature. A reaction mechanism to explain the data is derived. From the Arrhenius equation, the activation energies in the region of experimental temperatures are found to be from 5.49 to 9.15 kcal/mole. The concentration of excess oxygen in the nickel oxide seems to vary according to the sintering temperatures and periods and is the controlling factor in determining the type of kinetics followed by the catalytic reaction.
