Abstract: The present invention provides high-octane fuel, and a method of producing same. These fuels may be formulated to have a wide range of octane values and energy, and may effectively be used to replace 100 LL aviation fuel (known as AvGas), as well as high-octane, rocket, diesel, turbine engine fuels, as well as two-cycle, spark-ignited engine fuels.

Abstract: The present invention provides non-petroleum high-octane fuel derived from biomass sources, and a method of producing same. The method of production involves reducing the biomass feedstocks to sugars, fermenting the sugars using microorganisms or mutagens thereof to produce ethanol or acetic acid, converting the acetic acid or ethanol to acetone, and converting the acetone to mesitylene and isopentane, the major components of the renewable engine fuel. Trimerization of acetone can be carried out in the presence of a catalyst containing at least one metal selected from the group consisting of niobium, iron and manganese. The ethanol can be converted to mesitylene in a dehydration reaction in the presence of a catalyst of zinc oxide/calcium oxide, and unreacted ethanol and water separated from mesitylene by distillation.

Abstract: The present invention provides fully renewable turbine and diesel fuels created from biomass sources. In one embodiment, the fully renewable turbine fuel is comprised of mesitylene and at least one alkane. Preferably, the turbine fuel comprises from about 50 to 99 wt % mesitylene and from about 1 to 50 wt % of at least one alkane. In another embodiment the diesel fuel comprises mesitylene, octadecane, and optionally octane or nonane. Preferably, the diesel fuel comprises from about 50 to 99 wt % mesitylene, and from about 1 to 50 wt % octadecane. These biomass derived fuels may be formulated to have a wide range of cetane values and differing freezing and boiling points. A preferred biogenic turbine fuel comprises one or more synthetic paraffinic kerosenes (SPK) and/or hydroprocessed renewable jet (HRJ) fuel; and between about 8 to 25 vol % of mesitylene.
