Abstract

Catalytic system for the oxidative dehydrogenation of alkylaromatics (in particular ethylbenzene) or paraffins to the corresponding alkenylaromatics (in particular styrene) or to the corresponding olefins, consisting of:a vanadium oxide;a bismuth oxide;and a carrier based on magnesium,wherein the vanadium, expressed as V2O5, is in a quantity ranging from 1 to 15% by weight, preferably from 2 to 10%, the bismuth, expressed as Bi2O3, ranges from 2 to 30% by weight, preferably from 5 to 25% by weight, the complement to 100 being the carrier.
