Abstract

Platinum catalyst deactivation during aqueous alcohol oxidation is discussed, using the oxidation of methyl -D-glucopyranoside as an example. The most important causes of platinum deactivation are catalyst over-oxidation and catalyst poisoning. Deactivation by over-oxidation can be reversed by applying a redox-cycle, i.e. cyclic exposure to oxidative and reductive circumstances. A kinetic model for methyl -D-glycopyranoside oxidation, platinum deactivation, and reactivation is presented and implemented into a three-phase stirred slurry reactor model, clearly showing the advantages of redox-cycles.
