    Abstract

    Reconciling reaction rates between batch and fixed bed catalytic reactors for three-phase reactions is challenging because of mass transport resistances and reactor hydrodynamics. The ruthenium-catalyzed hydrogenation of lactic acid was examined in both stirred batch and trickle bed reactors in order to correlate the reaction rates observed therein. Within the intrinsic kinetic regime of operation, propylene glycol formation rates in both reactors correlate well with each other and are independent of catalyst loading in the batch reactor and feedstock flow rate in the trickle bed reactor. These results make it possible to predict performance in a trickle-bed reactor based on experiments conducted in bench-scale batch reactors.
