    Abstract: Balanced unleaded fuel compositions exhibiting: a pump octane rating of greater than 93; a T50 (maximum) of 104.4° C. (220° F.) and a T90 (maximum) of 165.6° C. (330° F.), as required under the CARB Phase 3 model; and, producing a higher average torque and/or higher average power output than commercially available fuels stated to meet the CARB Phase 3 model.

    Abstract: A gasoline blending components production system useful for producing both aromatics and gasoline blending components from naphtha. The production system includes a light hydrocracked naphtha splitter, a medium hydrocracked naphtha splitter, a naphtha hydrotreater, an isomerization unit, a continuous catalytic reformer and aromatics complex. The production system is operable to produce both refined benzene and para-xylene products in addition to medium hydrocracked naphtha, isomerate, a C7s cut and a C9+ cut, which are useful for gasoline blending without additional treatment. A method for producing gasoline blending components while maximizing aromatic production includes introducing both stabilized hydrocracked naphtha to the light hydrocracked naphtha splitter and straight run naphtha to the naphtha hydrotreater. Operating the production system produces three types of hydrocracked naphtha: a light hydrocracked naphtha, a medium hydrocracked naphtha and a heavy hydrocracked naphtha. Light and heavy hydrocracked naphtha are directed to the naphtha hydrotreater.
