Abstract
The kinetic study of the oxidative dehydrogenation of isobutyraldehyde, IBA, by the periodic pulse technique has been made to obtain some information on the improvement of the catalyst for the periodic pulse technique. The reaction rate to each product was experimentally and theoretically examined as a function of air pulse width, IBA pulse width and IBA partial pressure, and the rate was explained by assuming the following reaction scheme. IBA reacts with the oxygen retained by the catalyst to form methacrolein, MA. The IBA adsorbed on the oxidized surface is oxidized by the oxygen coming from the gas phase to form carbon monoxide and carbon dioxide. The adsorbed IBA desorbs as another oxidized product.
