Dynamic modelling of glucose oxidation with palladium catalyst deactivation in multifunctional CSTR: Benefits of periodic operation

Heterogeneously catalyzed oxidation of glucose in liquid phase was studied as a model reaction under conditions of reversible deactivation of a palladium catalyst. The proposed kinetics model fitted the experimental data very well. The model was used to explore benefits of a CSTR operation under forced periodic modulation of the gas feed stream. The periodic modulation makes it possible to optimize the catalyst reaction–reactivation processes in CSTR, so that the highest possible reactor productivity could be achieved for given input parameters. Under such operation of the multifunctional CSTR, the catalyst activity is long-term steady. Based on simulations, conditions of the highest possible CSTR productivity were identified for given operational parameters.
