Abstract

Abstract A new catalyst composition for converting hydrocarbons is disclosed. Also disclosed is a method for making the catalyst. The catalyst comprises a platinum group component and a phosphorous component with a porous support material. The catalyst is made by compositing a platinum group component with a porous support material and then contacting that composite with phosphorus or a compound of phosphorus. In a preferred embodiment of the invention a catalyst comprising platinum, phosphorus and chlorine with alumina 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 as a petrochemical feedstock.
