Abstract:The efficient utilization of the reaction heat in a catalytic oxidation system with lean reactants is an important aim in the processing industry and environmental engineering. In recent years, the adoption of reverse flow reactor (RFR) technology-which is known as an advanced process-enhancement method-in catalytic oxidation reactions has systematically been studied in the Research Institute of Industrial Catalysis and Reaction Engineering in Beijing University of Chemical Technology (BUCT). These studies have covered the theoretical basis, laboratory and pilot investigations, and scale-up to industrial plants. Detailed studies of the preparation of structured catalysts, the experimental operating performance of reverse flow catalytic oxidation reactors, process modeling of the reaction/heat transfer system, numerical solution methods for the differential equations concerned with the unsteady state operation reactor model, and control techniques have been carried out. On the basis of these studies, in cooperation with various partners, the relevant techniques have been integrated into a complete technology package with independent intellectual property rights. Several large-scale plants have been constructed for the destruction of low concentration methane from coal mine ventilation, and for devolatilization of the effluent from the decarbonizing towers of coal-to-oil plants. This technology has been shown to offer long-term and stable operation of industrial plants.
