Beschreibung
Zusammenfassung:	Process for the production of styrene which comprises: a) feeding to an alkylation unit a stream of benzene and a stream of recycled product containing ethylene; b) mixing the stream at the outlet of the alkylation unit, containing ethylbenzene, with a stream consisting of ethane; c) feeding the mixture thus obtained to a dehydrogenation unit containing a catalyst capable of contemporaneously dehydrogenating ethane and ethylbenzene; d) feeding the product leaving the dehydrogenation unit to a separation section to produce a stream essentially consisting of styrene and a stream containing ethylene; e) recycling the stream containing ethylene to the alkylation unit.
