Process for producing light olefins

A process for producing light olefins, comprising:

• hydrocracking a hydrocarbon feed stream in a hydrocracking reactor over a hydrocracking catalyst in the presence of a hydrocracking hydrogen stream at hydrocracking conditions to produce a hydrocracked stream;
• separating said hydrocracked stream to provide a recycle stream and a reforming charge stream;
• reforming said reforming charge stream over a reforming catalyst in a reforming unit to convert naphthenes to aromatics and produce a reformed stream;
• and
• charging said reformed stream to an NEP reactor to convert said reformed stream over an NEP catalyst in the presence of NEP hydrogen to produce a light paraffinic stream.

• separating said hydrocracked stream to provide a reforming charge stream and a recycle stream;
• recycling said recycle stream to the hydrocracking reactor;
• reforming said reforming charge stream over a reforming catalyst in a reforming unit to convert naphthenes to aromatics and produce a reformed stream, wherein said reforming charge stream comprises naphthenes and aromatics of at least 6 carbon atoms or at least 8 carbon atoms;
• and
• charging said reformed stream to an NEP reactor to convert said reformed stream over an NEP catalyst in the presence of NEP hydrogen to produce a light paraffinic stream.
