Abstract

Interest in new catalysts for alkanes isomerization, such as sulfated zirconia, has been increasing in the last years. These catalysts, due to their superacid character, have a good activity for this reaction but undergo a rapid deactivation. For sulfated zirconia catalysts, the effect of sulfates concentration on the activity and stability for alkanes isomerization is not clear. In this work, Pt/sulfated zirconia catalysts with different sulfates content were prepared by the impregnation method; characterized by X-ray diffraction, high-resolution Raman spectroscopy, infrared spectroscopy, and BET surface area; and evaluated in an experimental system for n-heptane isomerization.
