Systems for reforming a feedstock comprising paraffins and naphthenes. A first reactor containing a first reforming catalyst is operable to maintain a temperature and pressure that facilitates conversion of naphthenes in the feedstock to aromatics while facilitating conversion of less than 50 wt. % of paraffins in the feedstock to olefins. A first separator receives and separates the first effluent that is produced in the first reactor to produce a first fraction enriched in aromatics and a second fraction enriched in paraffins. A second reactor containing a second reforming catalyst is operable to maintain a temperature and pressure that facilitates conversion of at least 50 wt. % of paraffins in the second fraction to olefins. The system is operable to produce a liquid hydrocarbon product suitable for use as a blend component of a liquid transportation fuel.

The present disclosure relates to processes that catalytically convert a hydrocarbon feed stream predominantly comprising both isopentane and n-pentane to yield upgraded hydrocarbon products that are suitable for use either as a blend component of liquid transportation fuels or as an intermediate in the production of other value-added chemicals. The hydrocarbon feed stream is isomerized in a first reaction zone to convert at least a portion of the n-pentane to isopentane, followed by catalytic-activation of the isomerization effluent in a second reaction zone with an activation catalyst to produce an activation effluent. The process increases the conversion of the hydrocarbon feed stream to olefins and aromatics, while minimizing the production of C1-C4 light paraffins. Certain embodiments provide for further upgrading of at least a portion of the activation effluent by either oligomerization or alkylation.

A systems and method for manufacturing a base stock from an ethanol stream are described herein. An example method includes dehydrating an ethanol stream to form an impure ethylene mixture, recovering an ethylene stream from the impure ethylene mixture, and oligomerizing the ethylene stream to form a raw oligomer stream. A heavy olefinic stream is distilled from the raw oligomer stream. The heavy olefinic stream is hydro-processed to form a hydro-processed stream, and the hydro-processed stream is distilled to form the base stock.
