Disclosed herein is a fuel blend comprising a hydrocarbon based fuel; and particles that comprise magnesium and boron. Disclosed herein too is a method comprising blending a composition comprising a hydrocarbon based fuel and particles that comprise magnesium and boron to form a fuel blend.
1. A fuel blend comprising:
a hydrocarbon based fuel; and
a particulate mixture of boron particles, magnesium boride particles and magnesium oxide particles;
where the magnesium is present in an amount of 14 to 28 wt. %, and where the boron is present in an amount of 70 to 90 wt. % based on the total weight of the particulate mixture;
where the particulate mixture is present in an amount of 47 to 52 wt. % based on the total weight of the fuel blend.
2. The fuel blend of claim 1 , where the fuel blend comprises a slurry of the particulate mixture and the hydrocarbon based fuel.
3. The fuel blend of claim 1 , where the hydrocarbon based fuel has a carbon number distribution between about 5 and 16 and comprises branched and straight chain alkanes and naphthenes, alkylbenzenes, alkylnaphthalenes and olefins.
4. The fuel blend of claim 1 , where the hydrocarbon based fuel comprises alcohol based fuels, gasoline, diesel, kerosene, or a combination thereof.
5. The fuel blend of claim 1 , where the magnesium boride particles comprise MgB x particles, where x is an integer from 1 to 12.
6. The fuel blend of claim 1 , where the particulate mixture has an average particle size of 10 nanometers to 5 micrometers prior to being incorporated into the fuel blend.
7. The fuel blend of claim 1 , where a portion of the particulate mixture has an average particle size of 10 nanometers to less than 100 nanometers after being incorporated into the fuel blend and where this portion of the particles are suspended in the hydrocarbon based fuel.
8. The fuel blend of claim 1 , further comprising at least one of a surfactant and a dispersant.
9. The fuel blend of claim 8 , where the surfactant comprises succinimides, poly-isobutylene succinimide, octylamine, trioctylamine, sorbitan trioleate, a non-ionic surfactant that includes hydrophilic polyethylene oxide chains on a hydrocarbon oleophilic group, or a combination thereof, and where the surfactant is present in an amount of 1 to 15 wt %, based on a total weight of the fuel blend.
10. The fuel blend of claim 8 , where the dispersant comprises CaCO 3 microcrystals coated with an alkylsulfonate wetting agent, and where the dispersant is present in an amount of 1 to 15 wt %, based on a total weight of the fuel blend.
11. The fuel blend of claim 1 , where the fuel blend has a gravimetric energy density of 45 to 51 kilojoules per gram as determined via a bomb calorimetry test.
12. The fuel blend of claim 1 , where the fuel blend has a solution viscosity of 10 to 200 centipoise when measured using a Brookfield viscometer at room temperature and pressure.
13. A method comprising:
blending a composition comprising a hydrocarbon based fuel and a particulate mixture of boron particles, magnesium boride particles and magnesium oxide particles to form a fuel blend;
where the magnesium is present in an amount of 14 to 28 wt. %, and where the boron is present in an amount of 70 to 90 wt. % based on the total weight of the particulate mixture;
where the particulate mixture is present in an amount of 47 to 52 wt. % based on the total weight of the fuel blend.
14. The method of claim 13 , where the blending includes shearing the composition to reduce particle size.
15. The method of claim 13 , where the composition further comprises a surfactant and a dispersant.
