Patent ID: 8052938

Claim:
A reactor system comprising: a first reactor having an inlet, an outlet and a reaction zone, the first reactor is capable of receiving a feed stream having an oxygenate component and a hydrocarbon component and of converting a portion of the oxygenate component to a light olefin and alkylating a portion of the hydrocarbon component to form alkyl aromatic compounds, the light olefin and the alkyl aromatic compounds are included in a first effluent stream; a separator system in fluid communication with the outlet of the first reactor for receiving the first effluent stream of the first reactor and for providing a first product stream containing a C 3 olefin, a second stream containing a C 7 aromatic, and a third stream containing C 8 aromatic compounds; a first line connecting the separator system to the inlet of the first reactor for conveying the second stream to the first reactor; a second line in fluid communication with the separator system for conveying the C 3 olefin to a propylene recovery unit; and a third line in fluid communication with the separator system for conveying the C 8 aromatic compounds to a xylene recovery unit.
