The transient behavior of ethanol dehydration on/in heteropoly compounds was studied. Ethylene formation lasted for a long time after the ethanol feed had stopped, while ether formation decreased monotonously with time. A reaction model which includes the participation of sorbed alcohol was proposed: ethylene formation occurs through a unimolecular decomposition of ethanol, while ether formation takes place through a coupling of chemically activated ethanol with the physically sorbed one. Both reactions occur in the bulk phase of the compounds. Transient curves as well as kinetic behavior under the stationary reaction conditions could be satisfactorily simulated by this model for both products.
