Mesitylene as an octane enhancer for automotive gasoline, additive for jet fuel, and method of enhancing motor fuel octane and lowering jet fuel carbon emissions

Abstract

A motor fuel comprising gasoline comprising 70-99 wt % gasoline and 1 to 30 wt % of mesitylene. This fuel can advantageously contain conventional additives used in gasoline. The use of mesitylene in gasoline blend yields a fuel blend with a higher research octane number and motor octane number. In addition, an improved jet fuel is provided, having from 1-10 wt % mesitylene added to the jet fuel, having improved carbon emission characteristics while maintaining required specifications. Further, an improved bio-fuel is provided, which may function as a replacement for conventional Jet A/JP-8 fuel and has lowered carbon emission specifications, the bio-fuel comprised of 75-90 wt % synthetic parafinnic kerosene (SPK) and 10-25 wt % mesitylene.
