Abstract
The kinetics of isopentane dehydrogenation into isoamylenes and isopre ne in the presence of hydrogen and water vapor over potassium-, tin-, and indium-promoted platinum-alumina catalysts were studied. The rate equation was derived. Tin and indium promotion was shown to have no ef fect on the reaction kinetics and to increase the reaction rate and th e selectivity of the catalysts. The retardation of the reaction by iso amylenes and isoprene tends to decrease, while the inhibition effect c aused by water vapor aggravates.
