In the GLR model, hydrodynamics of a real GLR and kinetics of glucose oxidation by air over palladium catalyst are incorporated. The GLR model searches for optimal geometry of the target reactor. In the point of the GLR optimal geometry the reactor productivity is maximal for given input operational conditions. Algorithm of the GLR model is presented together with simulation results of the target GLR and with insight into the parametric sensitivity of the model. Effects of the reaction components concentrations and the gas phase superficial velocity on location of the target reactor optimal geometry and on the reactor productivity are discussed.
