  • Patent number: 10465129
    Abstract: Process for reforming a hydrocarbon feedstock comprising paraffins and naphthenes. A hydrocarbon feedstock is separated to produce a first fraction enriched in naphthenes and a second fraction that is enriched in paraffins. The first fraction is contacted with a first reforming catalyst in a first reactor that is maintained at a temperature and pressure that facilitates conversion of naphthenes to aromatics. The second fraction is contacted with a second reforming catalyst in a second reactor at a temperature and pressure that converts at least 50 wt. % of paraffins in the second fraction to olefins. The process produces a liquid hydrocarbon reformate product suitable for use as a blend component of a liquid transportation fuel.
