Microstructured reactor for consecutive heterogeneous/homogeneous gas phase reactions

摘要

Short reaction paths, small smounts of reactants as well as fast and effective changes in reaction conditions are outstanding features of microreaction systems. These characteristics are of interest especially with respect to very fast consecutive reaction sequences utilizing different thermal conditions or reactants. Here, a microreaxtor designed for combined heterogeneously catalyzed/homogeneous gas phase reactions is presented. Main features of the reactor are microstructured components located directly at the reaction zone. Focus of the work reported here is the feasibility of combined heterogeneous/homogeneous gas phase processes in microreaction systems by combining short distances and steep temperature gradients in order to assure fast processing of unstable reaction intermediates.
