Three case studies present different aspects of the identification of kinetic models in heterogeneous catalysis. The demonstrations are based on the real examples of laboratory catalytic hydrogenation experiments. The common target of all the studies is to demonstrate the possibilities of maximizing the reliability of parameter estimates for the limited experimental sets of data. The topics of the case studies include the comparison of Langmuir-Hinshelwood (LH) and non-stationary kinetic models, a discussion concerning the effects of invalid assumptions for catalyst surface coverage, and issues related to the design of experiments.
