More Information
Summary:The present invention is directed to an improved isomerization process employing a catalyst wherein the catalyst comprises a pair of cataly st particles of different acidity utilized either as distinct beds of such disc reteparticles or as a mixture of such discrete particles . The isomerization process utilizing such a catalyst produces a product which exhibits higher VI as compared to products produced using either catalyst component separately or using a single catalyst having the average acidity of the two discrete catal ysts.
