Abstract

The influence of indium on the properties of Pt-Re/Al₂O₃ catalysts used in naphtha reforming is studied. The addition of indium to the Pt-Re/Al₂O₃ catalyst produces a big decrease of acidity. It also produces an inhibition of the metal function, i.e., dehydrogenation and hydrogenolysis activity. The reaction of n-C₅ isomerization shows that indium addition decreases the total activity of the Pt-Re catalyst but increases the selectivity to the i-C₅ isomers. The selectivity to low cost light gases (C₁-C₃) is particularly decreased. The reaction of n-C₇ reforming showed that addition of indium increases the stability of the catalyst and the selectivity to aromatics, and decreases the production of light gases.
