Sažetak
The ·oscillatory states in the oxidation rate of H2 on nickel
were investigated by the CPD measurements. The oscillations were
found in the range of temperatures 433-673 K. and gas velocities
0.006-2.5 m/s. At . gas Velocities above 0.1 m/s oscillations in the
catalyst temperature and gas composition disappeared while CPD
oscillations remained, revealing the chemical cause of the oscillations.
A mathematical model is proposed based on assumption of
simultaneous oxidation and reduction of the surface. The model
predicts oscillatory states and its predictions are in semiquantitative
agreement with the experimental data.
