详细

The kinetic regularities of methylcyclohexane dehydrogenation into toluene and hydrogen on the supported Pt,Sn/γ-Al2O3 catalyst in the gas phase have been studied in detail. Based on the results of kinetic experiments, using the advancement and discrimination of hypotheses, an adequate structural kinetic model of the reversible process has been created. It is based on a mechanism that includes four routes involving the bifunctional active center of the catalyst and its two adsorption complexes: with hydrogen and with toluene.
