ABSTRACT:
C2–C30-alkanes are dehydrogenated in a process in which(i) ethylbenzene is dehydrogenated to styrene in a first part process to give a hydrogen-containing offgas stream, and(ii) one or more C2–C30-alkanes are dehydrogenated in the presence of a heterogeneous catalyst in one or more reaction zones in a second part process to give the corresponding olefins, with a hydrogen-containing gas stream being mixed into the reaction gas mixture of the dehydrogenation in at least one reaction zone,wherein at least part of the hydrogen-containing offgas stream obtained in the dehydrogenation of ethylbenzene is mixed into the reaction gas mixture of the alkane dehydrogenation.
