Processes and apparatuses for the production of olefins are provided. In an embodiment, a process for production of a process is provided for increasing light olefin yield comprising passing a hydrocarbon feedstream comprising paraffins, naphthenes and aromatic hydrocarbons to a catalytic reforming unit. The hydrocarbon feedstream is contacted with a reforming catalyst under mild reforming conditions suitable for converting naphthenes into aromatics while minimizing conversion of the paraffins, to provide a reforming effluent stream. The reforming effluent stream is passed to a solvent extraction unit to provide an overhead stream comprising predominantly paraffins and a bottoms stream comprising predominantly aromatics. Finally, the overhead stream is passed to a cracking unit to provide a product stream comprising the light olefins.
