Process for upgrading a hydrocarbonaceous feedstock

摘要

Process for upgrading a hydrocarbonaceous feedstock substantially boiling in the gasoline range, which process comprises: a) subjecting the feedstock to a separation treatment wherein normal paraffins and optionally mono-isoparaffins are separated from di-isoparaffins; b) recovering therefrom a first separation effluent stream comprising normal paraffins and optionally mono-isoparaffins and a second separation effluent stream comprising di-isoparaffins; c) separating at least part of the second separation effluent stream into a light fraction comprising hydrocarbons of the C6-C10 range and a heavy fraction comprising C8 and greater hydrocarbons; and d) subjecting at least part of the heavy fraction comprising C8 and greater hydrocarbons to a reforming step to produce a reformate. l
