Simplified procedure for design of catalytic combustors with periodic flowreversal

An extended simplified model, applicable to every cycle period, for the sim ulation of the behaviour of an adiabatic reverse-how reactor for the treatm ent of waste gases is presented and compared to the complete model. This mo del is based on the analogy with the steady countercurrent reactor and cons ists of simple equations that relate the main input and dimensional paramet ers of the reactor. Such a model permits the setting up the guidelines for the design of the reactor and to obtain some indications for its control sy stem, allowing the prediction of the limiting operating conditions for auto thermal operation.
