It was found that (a) the maximum rate of reduction of Pt and Pd ammine Y occurred at 300 and 250 °C, respectively; (b) decomposition of Pt ammine Y in air leads to formation of Pt metal—air is essentially an inert medium, although the oxidation of evolved NH3 is catalyzed by Pt; Pd is only partially reduced to metal when Pd ammine Y is decomposed in air; (c) decomposition in H2 effects reduction at much lower temperatures; (d) acid sites in the zeolite are always generated stoichiometrically by the decomposition of Pt and Pd ammines, whether in hydrogen, helium, or air. The maximum rate of reduction of Pt ammine Y at 300 °C correlates with reported maxima in dehydrogenation activity and Pt dispersion. In this study, the 300 °C calcined catalysts showed maximum n-hexane dehydrocyclization activity and selectivity as well as cyclohexane dehydrogenation.查看更多
