Claim Text:
1. A method for producing a butanol blended gasoline, comprising: (a) operating an oil refinery to produce a light distillate product from crude oil, wherein the oil refinery comprises one or more octane upgrading units; (b) feeding a naphtha feedstock to the one or more octane upgrading units to convert the naphtha feedstock to an upgraded naphtha product having a higher octane than an octane of the naphtha feedstock, wherein the light distillate product comprises the upgraded naphtha product; and (c) forming a blend of at least the light distillate product and an amount of butanol to produce a butanol blended gasoline, wherein the amount of upgraded naphtha product in the butanol blended gasoline is from about 10% to about 50% by volume of the gasoline, wherein throughput for the octane upgrading unit is less than throughput for the octane upgrading unit when the oil refinery is operated to produce a different light distillate product which is an automotive-grade gasoline free of alcohol.
