Annotation	Tanks-in-series based model was applied to aid design of gas-lift reactor (GLR), where oxidation reaction along with catalyst reversible deactivation proceeds. Heterogeneously catalyzed wet air oxidation of glucose dissolved in aqueous alkaline solution served as model reaction. Commercial 2.8% Pd/C catalyst was used in this study. Its advantage is activity at mild conditions with high selectivity towards salt of gluconic acid. But it gets deactivated by the action of oxygen quickly during the reaction course. Multifunctional gas-lift reactor allows the desired reaction, as well as the catalyst reactivation. Optimal design of the gas-lift reactor makes it possible to keep high and stable activity of the catalyst.
