Abstract

The transformation of n-decane was carried out on bifunctional Pt-HBEA catalysts obtained either by exchange of the HBEA zeolite with Pt, or by mixing various amounts of the HBEA zeolite with a Pt-impregnated alumina. Pt-exchanged HBEA was the most selective catalyst for n-decane isomerisation, which can be explained by a better proximity between acidic and hydrogenating sites and by a fast desorption of monobranched isomers through the small crystallites of the HBEA zeolite.
