Abstract
The influence of preparation conditions on the textural properties of Pt/SO42--ZrO2 has been studied. The presence of sulfate preserves a gr eat part of the small diameter pores after calcination, thus maintaini ng the specific surface area. Platinum is partially lost when sulfatio n takes place after platinum addition. The platinum containing catalys ts show good activity (conversion about 65%) and selectivity (about 94 %) for n-hexane isomerization, while SO42--ZrO2 presents a poor activi ty. The catalytic activity is independent of the order of platinum and sulfate addition.
