A monofunctional catalyst for the dehydrocyclization of paraffins, characterised in that it contains: 0.1 to 1.5% of platinum 0.1 to 1.5% of rhenium incorporated in the form of carbonyl a small proportion of sulphur introduced by a sulphur compound which is 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 is between 0.05 and 0.6, the support being a zeolitic crystalline aluminosilicate compensated to more than 90% by alkaline cations, having a pore diameter larger than 6.5 ANGSTROM . |
