The Effect of Platinum Content and Electronic State in Pt/WO3/ZrO2 Catalysts on Isomerization of n-heptane

The effect of concentration of the metallic component – platinum (0.1-2 wt.%) – and its electronic state in Pt/WO3/ZrO2 catalysts on characteristics of n-heptane isomerization was studied. It was found that a rise in the platinum concentration to 1.5 wt.% increases the yield of the target products o...

Description
Summary:The effect of concentration of the metallic component – platinum (0.1-2 wt.%) – and its electronic state in Pt/WO3/ZrO2 catalysts on characteristics of n-heptane isomerization was studied. It was found that a rise in the platinum concentration to 1.5 wt.% increases the yield of the target products of n-heptane isomerization – high-octane di- and trimethyl-substituted isomers (DTMS). Calcination of the catalyst in flowing air was shown to facilitate the formation of charged platinum, the presence of which enhances the catalyst activity.
