ABSTRACT:
A method for preparing an improved composition of matter whereby a solid catalyst comprising alumina derived from hydrous alumina predominating in alumina trihydrates and at least one platinum group component is used in hydrocarbon conversion service for a period of time to reduce the surface area of said solid catalyst to from about 20% to about 90% of the surface area of the original solid catalyst. This decreased area solid catalyst is treated with at least one metal promoter to produce a treated catalyst having improved properties. An improved method for hydrocarbon conversion using this treated catalyst is also disclosed.
