Abstract: Processes and systems for the production of heavy isoparaffinic hydrocarbons include feeding hydrogen and a mixed isoolefin stream, including C8-C12 olefins, isoolefins, and oligomers, and C8-C12+ hydrogenated hydrocarbons to a trickle-bed reactor system. The hydrogen and mixed isoolefin are reacted over a hydrogenation catalyst, producing a liquid effluent comprising hydrogenated hydrocarbons and unreacted olefins and oligomers, and a vapor effluent comprising hydrogenated hydrocarbons, hydrogen and unreacted olefins and oligomers. The liquid effluent is fed to a first heat exchanger, producing a cooled liquid effluent stream, which is combined with the vapor effluent, producing a mixed phase effluent. The mixed phase effluent is cooled in a second heat exchanger, producing a partially condensed effluent, which is fed to a drum, producing a vent stream, a hydrogenated product stream having greater than 95 wt % C8-C12 saturated hydrocarbons, and a hydrogenated recycle stream. The hydrogenated product stream may be provided to downstream blending systems.

Abstract: Systems and processes for the treatment of a naphtha range hydrocarbon feedstock comprising sulfur-containing compounds, nitrogen-containing compounds, olefins, diolefins, and aromatics. The systems and processes are configured to treat the naphtha range hydrocarbon feedstock to convert the sulfur-containing compounds, nitrogen-containing compounds, and olefins, diolefins while less than 2 wt % aromatics are hydrogenated, producing an olefin lean overheads fraction comprising less than 0.2 wt % olefins and less than 100 mg/kg sulfur and an aromatics rich fraction comprising less than 50 ppmw olefins, less than 0.5 ppmw sulfur and less than 0.5 ppmw nitrogen.
