ABSTRACT:
The present invention provides fully renewable engine fuels derived completely from biomass sources. In one embodiment the fully renewable engine fuel is comprised of one or more low carbon number esters, one or more pentosan-derivable furans, one or more aromatic hydrocarbon, one or more C4-C10straight chain alkanes derivable from polysaccharides, and one or more bio-oils. In addition, the fuel may contain triethanolamine. Such a lower octane renewable fuel may be utilized, for example, in automobile fuel, 100 LL aviation fuel applications, and turbine engine applications. These ethanol-based, fully renewable 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, and turbine engine fuels. In another embodiment, there is provided a synthetic high octane aviation fuel comprising isopentane and mesitylene, and process of producing same from a biomass.
