Abstract
Abstract A new catalyst for converting hydrocarbons, especially for reforming hydrocarbons, is disclosed. Also disclosed is a hydrocarbon conversion process using the catalyst as well as a method for making the catalyst. The catalyst comprises a platinum group component, a tin component, an indium component and a halogen component with a porous support material, wherein there is about 0.6 or more wt. %, on an elemental basis, indium present. In a preferred embodiment of the invention the catalyst is utilized in the catalytic reforming of hydrocarbons boiling in the gasoline range to produce a high octane reformate suitable for gasoline blending or a high aromatics content reformate suitable for use as a petrochemical feedstock.

Claim 8
Independent Claim
44 words
A method for manufacturing a catalyst which comprises incorporating a platinum group component, a tin component, an indium component and a halogen component with a porous support material so that there is about 0.6 or more wt. %, on an elemental basis, indium present.
Claim 9
Independent Claim
44 words
A method for manufacturing a catalyst which comprises incorporating a platinum group component, a tin component, an indium component and a halogen component with a porous support material so that there is about 0.6 or more wt. %, on an elemental basis, indium present.
