1. A process for converting naphtha comprising:
contacting a naphtha stream with a zeolitic catalyst at conditions which dehydrogenate paraffins to olefins, interconvert the olefins to lighter olefins and hydrogenate the lighter olefin to produce a light paraffin stream comprising ethane and propane.
