Kinetics and mechanism of selective oxidative dehydrogenation of n - amyl alcohol into valeraldehyde on modified zeolite catalyst CuZnPdCaA

Catalytic activity of zeolite CaA synthesized from zeolite NaA and modified by cations of metals Cu2+, Zn2+ and Pd2+ by the method of ion exchange in the reaction of partial oxidation of n-amyl alcohol into valeraldehyd, has been studied. It revealed that metal-zeolite catalyst CaA synthesized from zeolite NaA and containing 3.0 wt.% Cu 2+, 2.0 wt.% Zn2+ and 0.1 wt.% Pd2+ displays the highest activity and selectivity in the reaction. Also, kinetic regularities of the reaction on the said catalyst have examined. On the basis of the experimental data, a probable phasic mechanism has been suggested and a theoretically substantiated kinetic model of the reaction developed.
