    摘要: A process for the production of low sulfur, low olefin gasoline wherein a cracked naphtha, such as a full boiling range cracked naphtha, is first separated by fractional distillation into at least two fractions while simultaneously selectively hydrogenating the polyunsaturated compounds contained therein. The mono olefins in the light fraction are then subjected to etherification with alcohol to produce ethers or hydration with water to produce alcohols. The heavy fraction is subjected to sulfur removal by hydrodesulfurization or chemisorption. The two fractions are then combined to produce a low sulfur, low olefin gasoline.

    摘要: A fuel or fuel blendstock comprising ethanol, ethyl ethers, olefins, and alkanes. In some embodiments, the fuel or fuel blendstock of claim 1, wherein the fuel or fuel blendstock may have an octane number greater than 92 (RON+MON)/2). In other embodiments, the fuel or fuel blendstock may have a Reid vapor pressure less than 7.2 psi. Also disclosed is a process for the production of a fuel, the process including: contacting ethanol and at least one gasoline fraction including alkanes and olefins in the presence of a catalyst to form a fuel mixture including ethyl ethers, alkanes, unreacted olefins, and unreacted ethanol; and recovering the fuel mixture for use as a gasoline or gasoline blendstock without separation of the ethanol from the fuel mixture.
