Abstract
Cyclohexane dehydrogenation was used as a model reaction to study the dehydrogenation function of Pt/Al2O3 catalysts. Fresh and coked cataly sts were tested in two ranges of reaction conditions: model conditions (T=280-340 degrees C, P=1 atm) and the conditions used in the naphtha reforming process (T=420-460 degrees C, P=15 atm). Intrinsic properti es of the dehydrogenation active centers were found to be identical th roughout the experimental conditions. The coke deposits only block a p art of the active centers without their qualitative modification.
