Hydroisomerization of benzene-containing gasoline fractions on a Pt/SO 2−4 -ZrO2-Al2O3 catalyst: III. The hydrogenating properties of the catalyst

Kinetics and Catalysis Aims and scope Submit manuscript

Abstract

The properties and state of platinum in Pt/SO 2−4 -ZrO2-Al2O3 catalysts with various alumina contents have been investigated in benzene hydrogenation as a model reaction using IR spectroscopy, temperature-programmed reduction, and H2 chemisorption. As the Al2O3 content is raised, the hydrogenating activity of the catalyst increases, which is due to the increasing proportion of metallic platinum on the surface.
