| Inhoud: |
The use of feedback-induced bifurcation experiments for discriminating between rival models for the CO-02 reaction over supported silver is investigated. Model parameters are estimated or bounded by fitting the postulated kinetic mechanisms to steady-state and transient step-response data. Experimental steady-state bifurcation data is accurately reproduced by the models but each model fails to simulate adequately the Hopf bifurcation results. The dynamic bifurcation results are found to be sensitive to small time-scale dynamics that could not be resolved from the step-response experiments. Long transients in the catalyst activity are observed that cannot be reproduced by the kinetic models. |
