Abstract

Alkenyl benzenes by dehydrogenating alkyl benzenes. A gas mixture contg. >=10 vol. % of one or more alkyl benzenes and >=3 vol. % SO2, is passed at 350-750 degrees C for short times over an activated carbon catalyst (pref. of surface area 300-2000 (esp. 1200-1400)m2/g). The catalyst is very active, stable and esp. selective to styrene.
