Abstract:
A catalytic reforming process using catalysts containing a carrier, platinum, rhenium and optionally at least one metal selected from the group consisting of tin, germanium, lead, indium, thallium and titanium, arranged in several successive catalyst beds wherein the catalyst of the first bed has a Re/Pt ratio higher than the Re/Pt ratio of the catalyst used in the last bed, said catalyst of the last bed containing at least 0.08% of rhenium in proportion to the carrier. The catalysts preferably contain at least one halogen in an amount, expressed in proportion to the carrier, from 0.1 to 15%, said carrier preferably consisting mainly of alumina. In a preferred embodiment 3 successive catalyst beds are used wherein the Re/Pt ratios are, as a whole, decreasing from the first bed to the last bed.
