Oscillatory behavior during CO oxidation over Pd supported on glass fibers: experimental study and mathematical modeling

The oscillatory behavior during CO oxidation over Pd supported on glass fib ers was studied in a recycle reactor. The properties of oscillations as a f unction of temperature and inlet CO concentration were investigated in deta il. The peculiarity of the observed oscillations is their long period up to 6 h. Mathematical model considering oxidation-reduction processes of the P d has been developed to describe the experimental results. The model accoun ts for the observed reaction rate dependence on the CO inlet concentration, the region of oscillations and the dependence of the oscillatory behavior upon temperature and CO inlet concentration.
