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. Another preferred biogenic turbine fuel is a blend of about 50% petroleum-based fuel; and about 50% of one or more of synthetic paraffinic kerosenes (SPK) and/or hydroprocessed renewable jet fuel (HRJ), and mesitylene.
