Abstract

Abstract In this work, the modifying effect of alkaline metals (Li, Na and K) is studied on the acid properties of the support and on the behavior of PtSn/γ-Al2O3 catalytic systems, in the isobutane dehydrogenation. The isopropyl alcohol transformation rate decreases sharply with the addition of alkaline metals, according to the sequence Li
