External Catalytic Packed-Bed Palladium Membrane Reactor with Baffle Rings

Abstract

The membrane reactor in this work is a double tubular reactor equipped with a palladium-ceramic composite tube as inner tube and packed with catalysts in the annular part between the inner and outer tubes. Further, two kinds of baffle rings are in turn inserted into the catalytic bed to decrease radial gradients of concentration and temperature profiles by regulating gas flow patterns.
This proposed reactor is simulated by using dehydrogenation of cyclohexane as a model reaction. The efficiency of baffle rings was confirmed by calculating the conversions and mole fractions of hydrogen iunder various conditions of total pressure, temperature, and feed mole fraction, as well as the standard conditions.
