Abstract

A formulation and methods for making high energy organic fuels that incorporate suspended metal particles with metal particle sized ranging from 33 nm to 5 micron. The hybrid organic fuels contain superior density and/or energy content to conventional liquid organic fuels. These hybrid organic fuels used in combination with metal particle afford fuels with 5 to 80% more net heat of combustion (based on volume). These fuels should extend the distant range for jets, liquid rocket engines, SCRAM jet engines, and improve energy content in fuel-air explosive applications such as fuel-air explosives and in the Multi-Effects Weapons System (MEWS) where the fuel is used both for propulsion and explosive effects.

First claim

What is claimed is:

1. A method for producing quadricyclanes, comprising:
providing at least one multifunctionalized acetylenic core having at least one to four arms,

wherein:
n is an integer from 1 to 10 and wherein each said arm is replaced with a hydrogen or suitable alkyl or aromatic group;
X is selected from the group consisting of carbon, silicon, boron, or any combination thereof;
R is selected from the group consisting of alkyl(C1 to C8 methyl to octyl); and
wherein at least one said multifunctionalized acetylenic core is reacted with conjugated dienes or any composition having at least one ring strain molecule and subjected to light and at least one fixed bed catalyst to produce quadricyclanes having ring strain-molecules.

2. The method according to claim 1 , wherein said X is selected from the group consisting of borane (BH 3 ) or other borane based molecules having at least on B—H group and any combination of alky or aromatic substituents.

3. The method according to claim 1 , wherein said X is silicon including one to four hydrogens and any combinations of alkyl or aromatic substituents.

4. A method for making hybrid metallized organic fuels, comprising:
coating metal nanoparticles with a monolayer of long chain aliphatic acids or with perfluoroacid to produce modified metal nanoparticles for enhanced particle dispersion; or
coating with metal nanoparticles with quadricyclanes having ring strain-molecules;
wherein said quadricyclanes have at least one multifunctionalized acetylenic core having at least one to four arms,

wherein said quadricyclanes:
n is an integer from 1 to 21 and wherein each said arm is replaced with a hydrogen or suitable alkyl or aromatic group;
X is selected from the group consisting of carbon, silicon, boron, or any combination thereof;
R is selected from the group consisting of alkyl(C1 to C8 methyl to octyl); and
wherein at least one said multifunctionalized acetylenic core is reacted with conjugated dienes or any composition having at least one ring strain molecule and subjected to light and at least one fixed bed catalyst to produce said quadricyclanes having ring strain-molecules.

5. The method according to claim 4 , wherein said long chain aliphatic acids are selected from the group consisting of palmitic acid, stearic acid, long chained organic acids, branched chained acids, C 7 H 15 CO 2 H to C 21 H 43 CO 2 H Diacids, and HO 2 C—(CH 2 )nCO 2 H, wherein said n=7 to 21.

6. The method according to claim 4 , wherein said metal nanoparticles are selected from the group consisting of aluminum particles or powders, nano boron, and nano Ti.

7. The method according to claim 4 , wherein said metal nanoparticles having a particle size in the range from about 30 to about 99 nm.

8. The method according to claim 4 , wherein said metal particles are aluminum having a particle size ranging from about 0.1 to about 5 microns.

9. The methods according to claim 4 , wherein said hybrid metallized organic fuels have a 50-50 wt-% blend of nanoaluminum.

10. The method according to claim 4 , wherein at least about 80% to about 99% of the surface of said modified metal nanoparticles are coated with said quadricyclanes having ring strain-molecules.

11. The method according to claim 4 , wherein at least one said perfluoroacid is selected from the group consisting of perflouro nonadecanoic acid and C 7 F 15 CO 2 H to C 21 F 43 CO 2 H.

12. The method according to claim 4 , wherein said hybrid metallized organic fuels are blended with JP-5 and/or JP-10.

13. The methods according to claim 12 , wherein said JP-5 or JP-10 having a blend of about 0.1% by weight percentage to about 50 by weight percentage.

14. The method according to claim 12 , wherein said hybrid metallized organic fuels are blended with JP-5 and/or JP-10 having a heat of combustion of total fuel energy ranging from about 60 MJ/L to about 62 MJ/L.

15. Hybrid metallized organic fuels produced by the methods of claim 4 .

16. Quadricyclanes produced by the methods of claim 1 .

17. Hybrid metallized organic fuel blends with JP-5 and/or JP-10 produced by the methods in claim 12 .
