Abstract

The kinetics and mechanism of the oxidative dehydrogenation of cyclohexane over copper exchanged Y zeolites were studied. Benzene was identified as the primary product with cyclohexene and methylcyclopentane as secondary products. The associative adsorption of oxygen is proposed as the rate determining step. The levels of cyclohexane conversion were correlated with such diverse factors as the reaction temperature, Cu2+ cation loading, Cu2+ cation location and the extent of coke formation. The oxidative dehydrogenation of methylcyclohexane to toluene is also considered. The oxidative dehydrogenation of both cyclohexane and methylcyclohexane is shown to be strongly dependent on the nature of the alkali metal co-cation.
