Abstract: The kinetics of oxidative dehydrogenation of butene-2 over Fe-Zn-My-Cr spinel catalyst has been investigated in a flow-recirculation glass reactor. The kinetics of oxidative dehydrogenation of butene-2 obeyed the Redox mechanism of three steps. The reduction step of catalyst with butene-2 and reoxidation step of reduced catalyst with oxygen were investigated by the pulse method. The heat of adsoption of butene-2 was determined by the pulse method. The kinetics of deep oxidation of butene-2 and butadiene obeyed the empirical rate equation. The values of parameters of kinetic equations were estimated by the method of orthogonal design. It has be shown that the rate of oxidative dehydrogenation of butene-2 was faster than the rate of butene-1.
