Abstract: 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.

Abstract: A process for increasing a yield of an isomerization zone by removing at least a portion of the C6 cyclic hydrocarbons from a stream having iC4 hydrocarbons, iC5 hydrocarbons, and iC6 hydrocarbons prior to the stream being passed into the same isomerization zone. Suppression of the iC4 hydrocarbons does not occur, allowing the iC4 hydrocarbons to be isomerized in the same isomerization zone as the iC5 hydrocarbons and iC6 hydrocarbons.
