Zusammenfassung:Systems and methods for producing light olefins and BTX are disclosed. A feed stream comprising mixed C4 paraffins is first separated into a first stream comprising primarily isobutane, and a second stream comprising primarily n-butane. The first stream is processed in a catalytic cracking unit and the second stream is processed in a steam cracking unit. The resulting streams from the catalytic cracking unit and the steam cracking unit are separated to form product streams including an ethylene stream, a propylene stream, and a BTX stream.
