Influence of synthesis conditions on the stability and regeneration of mechanical mixtures of Pt/Al_2O_3 and SO_4/ZrO_2 in the isomerization of n-hexane

摘要

The influence of mechanical mixtures molding conditions and the ratio of the metallic and acid components on the stability in the n-hexane isomerization was studied. It is shown that an increase in the pressure used in molding and also double molding results in an increase in the stability of the mixture catalysts. In addition, catalysts prepared using double molding are more regenerable during the hydrogen treatment, which makes this technique preferable for use in the synthesis of bifunctional catalysts for basic research.
