| Abstract |
Toluene hydrogenation was studied over model catalysts with a fixed hydrogenating function (Pt/Al2O3) mechanically mixed with either HUSY or HBEA zeolites. Such mechanical mixtures showed improved platinum turnover frequencies compared to single Pt/Al2O3. Comparing to Pt-impregnated zeolite catalysts, the mechanical mixtures have lower activities per site showing that the contribution of acid sites decreases (and so the hydrogenating activity) with increased distance between Pt clusters and acid sites. Therefore, toluene hydrogenation can be used as a powerful tool to evaluate Pt-add site intimacy in bifunctional catalysts. (C) 2016 Elsevier B.V. All rights reserved. |
