A process for reforming a hydrocarbon feedstock, comprising: a) providing a hydrocarbon feedstock comprising paraffins and naphthenes, each of which comprises from four to twelve carbon atoms, wherein the boiling point range of the hydrocarbon feedstock ranges from about -12 °C to about 230 °C; b) contacting the hydrocarbon feedstock with a first reforming catalyst at a temperature in the range from 454 0 C (800 0 F) to 593 0 C (1100 0 F), a pressure in the range from 3 bar to 30 bar and a hydrogen to hydrocarbon molar ratio from 2:1 to 15:1 that facilitates the catalytic aromatization of naphthenes in the hydrocarbon feedstock, thereby converting the hydrocarbon feedstock to a first reformer effluent characterized by an increased research octane number and increased wt. % of aromatics, wherein the contacting catalytically converts less than 50% of paraffins in the hydrocarbon feedstock, wherein the first reforming catalyst comprises a solid support that contains acidic catalytic sites; c) separating the first reformer effluent into a first fraction and a second fraction, wherein the first fraction is enriched in aromatics and is suitable for use as a blend component of a liquid transportation fuel, and the second fraction is enriched in paraffins; d) combining the second fraction with a second reforming catalyst at a temperature in the range from 399 0 C (750 0 F) to about 677 0 C (1250 0 F), a pressure in the range from 1 bar to 34.5 bar, a molar ratio of hydrogen to hydrocarbon within the range from 0 to 1, a molar water to hydrocarbon ratio in the range from 0.1: 1 to 10: 1, a diluent liquid weight hourly space velocity in the range from 0.1 to 30 hr -1, optionally wherein the diluent is CO 2, H 2 O (as steam) or N 2, and a liquid weight hourly space velocity in the range from 0.5 to 12 hr -1 on a weight hydrocarbon rate per weight catalyst basis, that facilitates catalytic dehydrogenation of at least 50% of the paraffins in the second fraction by the second reforming catalyst, thereby producing a second reformer effluent that comprises predominantly olefins, unreacted paraffins and residual aromatics and is characterized by an increased research octane number relative to the second fraction, wherein the second reforming catalyst comprises Group II aluminate spinels according to the formula M(AlO 2) 2 or MO.Al 2 O 3, wherein M is a divalent Group IIA or Group IIB metal, and wherein the second reforming catalyst further comprises at least one of: 1) a catalytically-effective amount of at least one metal from Group VIIIB of the Periodic Table, and 2) at least one co-promoter selected from the group consisting of As, Sn, Pb, Ge and Group IA metals, wherein the second reforming catalyst comprises a solid support that does not contain acidic sites. a) providing a hydrocarbon feedstock comprising paraffins and naphthenes, each of which comprises from four to twelve carbon atoms, wherein the boiling point range of the hydrocarbon feedstock ranges from about -12 °C to about 230 °C;
