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

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.
