Claims22
A reforming catalyst comprising platinum, at least one promoter metal selected from the group formed by rhenium and iridium, at least one halogen selected from the group formed by fluorine, chlorine, bromine and iodine, and an alumina support modified by the inclusion of a sulphur and phosphorus content in the form of PO4 and SO4, wherein the sulphur content in the alumina support is in the range of 500 to 1200 ppm by weight with respect to the total support weight, and the phosphorous content in the alumina support is in the range of 0.04% to 1% by weight with respect to the total support weight, wherein the catalyst contains at least some of said sulphur and phosphorus in the form of PO4 and SO4.
