Abstract

The influence of preparation conditions on the textural properties of Pt/SO4 2−−ZrO2 has been studied. The presence of sulfate preserves a great part of the small diameter pores after calcination, thus maintaining the specific surface area. Platinum is partially lost when sulfation takes place after platinum addition. The platinum containing catalysts show good activity (conversion about 65%) and selectivity (about 94%) forn-hexane isomerization, while SO4 2−−ZrO2 presents a poor activity. The catalytic activity is independent of the order of platinum and sulfate addition.
