Abstract

Alkylaromatic hydrocarbons are dehydrogenated into alkenylaromatic hydrocarbons by contacting them in the absence of molecular oxygen with a supported catalyst of the redox type wherein the metal in the catalyst is at a valency such that it is not in its most reduced state, and the catalyst is regenerated before being contacted with fresh feed.
