Hommes, Arne published the artcileAerobic oxidation of benzyl alcohol in a slug flow microreactor: Influence of liquid film wetting on mass transfer, Quality Control of 140-11-4, the main research area is oxidation benzyl alc slug microreactor film wetting mass transfer.
Homogeneous Co/Mn/Br catalyzed aerobic oxidation of benzyl alc. in acetic acid to benzaldehyde was performed in polytetrafluoroethylene microreactors operated under slug flow at temperatures up to 150° and pressures up to 5 bar. Depending on the bubble velocity and length, a wetted or dewetted slug flow was observed, characterized typically by a complete or partially wetting liquid film around the bubble body. The latter flow suffered from a limited interfacial area for mass transfer. Experiments at temperatures up to ∼90° were under kinetic control given no product yield difference under wetted and dewetted slug flows and were used to establish a simplified kinetic expression (first order in benzyl alc. and zero order in oxygen). This allows to develop a mass transfer model combined with an instantaneous reaction regime that well described the exptl. results at higher temperatures where mass transfer was limiting in the dewetted slug flow.
