Abstract
The use of a novel catalyst in a reforming process is disclosed. The catalyst comprises a refractory inorganic oxide, platinum-group metal, Group IVA(IUPAC 14) metal, indium and lanthanide-series metal. Utilization of this catalyst in the conversion of hydrocarbons, especially in a reforming process, results in significantly improved selectivity to the desired gasoline or aromatics products.
Claims3
A process for the catalytic reforming of a naphtha feedstock which comprises contacting the feedstock at reforming conditions including a temperature of about 315° to 600° C., a pressure of about 100 kPa to 7 MPa (abs), a liquid hourly space velocity of about 0.1 to 20 hr−1, and a mole ratio of hydrogen to hydrocarbon feed of about 1 to 20, with a catalytic composite having enhanced conversion of paraffins to aromatics comprising a combination of a refractory inorganic oxide support with from about 0.1 to 10 mass-% on an elemental basis of a halogen component, about 0.01 to 2 mass-% on an elemental basis of a platinum-group metal component, about 0.01 to 5 mass-% on an elemental basis of a Group IVA(IUPAC 14) metal component selected from the group consisting of tin and germanium, about 0.1 to 5 mass-% on an elemental basis of an indium component and about 0.05 to 5 mass-% on an elemental basis of a lanthanum metal component.
