Abstract
A novel catalyst and the use thereof in a reforming process is disclosed. The catalyst comprises a refractory inorganic oxide, platinum-group metal, Group IVA(IUPAC 14) metal, and europium in a specified ratio. Utilization of this catalyst in the reforming of hydrocarbons, especially in reforming, results in significantly improved selectivity to the desired gasoline or aromatics product.

A catalytic composite comprising a combination of a refractory inorganic oxide support with about 0.01 to 5 mass % on an elemental basis of a Group IVA(IUPAC 14) metal component, about 0.01 to 2 mass % on an elemental basis of a platinum-group metal component, and about 0.05 to 5 mass % on an elemental basis of a europium component wherein more than about 50% of the europium is present as EuO and wherein the atomic ratio of europium to platinum-group metal is at least about 1.3.
A catalytic composite comprising a combination of an alumina support with about 0.01 to 5 mass % on an elemental basis of a tin component, about 0.01 to 2 mass % on an elemental basis of a platinum component, about 0.1 to 5 mass % on an elemental basis of an europium component wherein the atomic ratio of europium to platinum is at least about 1.3, and from about 0.1 to 10 mass % of a halogen component.
A process for the catalytic reforming of a naphtha feedstock which comprises contacting the feedstock at reforming conditions including a temperature of about 425.degree. to 565.degree. C., a pressure of about 350 to 2500 kPa (ga), a liquid hourly space velocity of about 1 to 5 hr.sup.-1, and a mole ratio of hydrogen to naphtha feedstock of about 2 to 10, with a catalytic composite comprising a combination of a refractory inorganic oxide support with about 0.01 to 5 mass % on an elemental basis of a Group IVA(IUPAC 14) metal component, about 0.01 to 2 mass % on an elemental basis of a platinum-group metal component, and about 0.1 to 5 mass % on an elemental basis of a europium component, wherein more than about 50% of the europium is present as EuO and wherein the atomic ratio of europium to platinum-group metal is at least about 1.3.
