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.
Claims6
A process for converting hydrocarbons which comprises contacting the hydrocarbons at reforming conditions with a catalyst made by the method of
- (a) compositing a platinum group component with a porous support material,
- (b) contacting the composite from step (a) with phosphorus or a compound of phosphorus at a temperature less than 700.degree. F. so that the phosphorus to platinum group component atomic ratio is greater than 0.5, and
- (c) then reducing the composite from step (b) without an intermediate oxidation step.
