Abstract
Monofunctional dehydrocyclization catalyst of paraffins, characterized in that it contains: 0.1 to 1.5% platinum, o.1 to 1.5% rhenium incorporated in the form of carbonyl, a small proportion of sulphur introduced by a sulphur compound reducible or decomposable by hydrogen such that the ratio x of the number of sulphur atoms to the number of platinum and rhenium atoms deposited on the catalyst be comprised between 0.05 and 0.6, the carrier being constituted by a zeolitic crystalline aluminosilicate compensated in more than 90% by alkaline cations having a pore diameter of more than 6.5 Angstroms.
