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.

Claims (8)

1. A 100 octane aviation fuel comprising: (a) 70-85 wt % of sym-trimethyl benzene (mesitylene); and (b) 15-30 wt % of isopentane, wherein the fuel has a motor octane number of 99.5 or greater, and a Reid vapor pressure of from 5.5 to 7.1 psi.

2. A 100 octane aviation fuel consisting essentially of: (a) 70-85 wt % of sym-trimethyl benzene (mesitylene); and (b) 15-30 wt % of isopentane, wherein the fuel has a motor octane number of 99.5 or greater, and a Reid vapor pressure of from 5.5 to 7.1 psi.

3. A 100 octane aviation fuel consisting of: (a) 70-85 wt % of sym-trimethyl benzene (mesitylene); and (b) 15-30 wt % of isopentane, wherein the fuel has a motor octane number of 99.5 or greater, and a Reid vapor pressure of from 5.5 to 7.1 psi.

4. A high octane aviation fuel comprising: (a) 60-85 wt % of sym-trimethyl benzene (mesitylene), and (b) 15-40 wt % of isopentane, wherein the fuel has a motor octane number of 99.5 or greater, and a Reid vapor pressure of from 5.5 to 7.1 psi.

5. The aviation fuel of claim 4 , wherein the mesitylene is present in an amount of between about 70 to 85 wt %.

6. The aviation fuel of claim 4 , wherein the isopentane is present in an amount of between about 15 to 30 wt %.

7. A high octane fuel comprising: (a) 70-85 wt % of sym-trimethyl benzene (mesitylene); and (b) 15-30 wt % of isopentane, wherein the fuel is an aviation fuel having a motor octane number of 99.5 or greater, and a Reid vapor pressure of from 5.5 to 7.1 psi.

8. A 100 octane aviation fuel comprising: (a) 70-85 wt % of sym-trimethyl benzene (mesitylene); and (b) 15-30 wt % of isopentane, wherein the fuel has a motor octane number of greater than 99.5, and a Reid vapor pressure of from 5.5 to 7.1 psi.
