Title
Microstructured Reactors for Heterogeneous Reactions
Microstructured Reactors for Heterogeneous Reactions Abstract: In recent years the use of microstructured reactors to produce a variety of chemicals has significantly increased. The successful implementation of such reactors requires the integration of competencies from material science catalysis chemical engineering and mechanical engineering. In this talk the design fabrication and applications of two types of microstructured reactors ( viz. monoliths and microchannel reactors) will be presented. For the last 3 decades monolith catalysts have been used for treatment of automobile exhaust and for selective reduction of NOx in flue gases. However their use in other gas-solid and multiphase catalytic reactions has not been fully exploited. The characteristics and preparation of monolith reactors will be briefly presented and their performance in some specific gas- solid reactions and multiphase reactions discussed. It will be shown that depending on the relative rates of mass transfer and reaction it is possible to achieve higher selectivities and/or higher productivities in monolith reactors than in conventional reactors. In the second part of the talk the use of microchannel reactors for producing hydrogen from ethanol will be presented. The fabrication of the microchannels on the metal substrate coating of the catalyst and support on the microchannels assembly of the microchannel reactor and different heat integration strategies will be discussed.
