NOVELTY - Increasing (I) volume of fuel mixture by chemically and physically blending ethanol fraction and at least one gasoline fraction, comprises: (a1) contacting ethanol fraction and at least one gasoline fraction, where the gasoline fraction comprises mixture of alkanes and olefins, in presence of etherification catalyst to form fuel mixture, and fuel mixture comprises ethyl ethers, alkanes, unreacted olefins, and unreacted ethanol; (b1) recovering fuel mixture; and (c1) using the fuel mixture as a gasoline or gasoline blendstock without separation of the ethanol from the fuel mixture.    USE - The processes are useful for increasing volume of fuel mixture by chemically and physically blending an ethanol fraction and at least one gasoline fraction, and chemically and physically blending ethanol and at least one gasoline fraction to produce a fuel.    ADVANTAGE - The processes: provide simplified etherification process, where the ethanol recovery section is completely eliminated saving both capital and operating costs; provide ethanol while reducing automotive emissions, effectively reducing olefins in the gasoline at a profit.    DETAILED DESCRIPTION - Increasing (I) the volume of a fuel mixture by chemically and physically blending an ethanol fraction and at least one gasoline fraction, comprises: (a1) contacting the ethanol fraction and at least one gasoline fraction, where the at least one gasoline fraction comprises a mixture of alkanes and olefins, in the presence of an etherification catalyst to form the fuel mixture, the fuel mixture comprises ethyl ethers, alkanes, unreacted olefins, and unreacted ethanol; (b1) recovering the fuel mixture; and (c1) using the fuel mixture as a gasoline or gasoline blendstock without separation of the ethanol from the fuel mixture, where the process chemically and physically blends the ethanol fraction into the gasoline fraction and thus provides an increase in the volume of barrels per day by at least 10% compared to a fuel mixture produced by a splash blend only process. INDEPENDENT CLAIMS are also included for (1a) chemically (II) and physically blending ethanol and at least one gasoline fraction to produce a fuel, comprising steps (a1)-(c1) as above per se, where the chemically and physically blended fuel mixture has a lower American society for testing and materials D86 5% temperature than a splash blended fuel mixture having an equivalent oxygen content and Reid vapor pressure and (2a) chemically (III) and physically blending ethanol and at least one gasoline fraction to produce a fuel, comprising feeding ethanol at least one gasoline fraction comprising alkanes and olefins to a fixed-bed reactor system containing at least one etherification reaction zone, and steps (b1) and (c1) as above per se, where the fuel mixture contains a greater quantity of C4 and/or C5 hydrocarbons compared to a fuel mixture produced by a splash blend only process.
