Abstract

A novel catalyst composite for use in the dehydrogenation of paraffins to the corresponding monoolefins said composite incorporating within its spatial geometry on a percentage by weight basis a predetermined concentration gradient of a noble metal, a metal of Group IV A, a metal of Group III A, an alkali or alkaline earth metal element, a halogen; and a metal of Group VIII selected from. Fe, Co and Ni provided on a high surface area mesoporous support and a process for the preparation thereof.
