摘要：
Cyclohexane dehydrogenation was used as a model reaction to study the dehydrogenation function of Pt/Al2O3 catalysts. Fresh and coked catalysts were tested in two ranges of reaction conditions: model conditions (T=280–340°C, P=1 atm) and the conditions used in the naphtha reforming process (T=420–460°C, P=15 atm). Intrinsic properties of the dehydrogenation active centers were found to be identical throughout the experimental conditions. The coke deposits only block a part of the active centers without their qualitative modification.
