Abstract

This alternative fuel is a reclaimed waste product which has a solid, particulate consistency at ambient temperature. The fuel comprises a composite of petroleum pitch and a powder coating. The powder coating penetrates into the surface of the pitch. The powder coating is recycled ash, pulverized coal, or pulverized petroleum coke.

Claims (22)

1. A method of utilizing a petroleum pitch fuel with a recyclable powder coating, the method comprising:

applying a recyclable powder ash coating positioned to coat an outer surface of a plurality of selected petroleum pitch forms and at least partially penetrate the outer surface of the petroleum pitch forms during solidification, to produce a penetrated ash coated petroleum pitch form;

providing the penetrated ash coated petroleum pitch form as a combustion fuel;

combusting the penetrated ash coated petroleum pitch form either singly or in combination with coal;

reclaiming the recyclable powder ash coating as a reclaimed ash; and

applying the reclaimed ash as the recyclable powder ash coating to the outer surface of a plurality of selected petroleum pitch forms, thereby to produce less total ash when combusting recyclable powder coated petroleum pitch fuel.

2. The method of claim 1 , wherein the recyclable powder ash coating comprises one or more of a recycled ash, a powdered ash, a recycled waste ash, a reclaimed ash, or a coal ash.

3. The method of claim 1 , wherein each of the selected petroleum pitch forms comprises a solvent deasphalted petroleum pitch.

4. The method of claim 1 , wherein each of the selected petroleum pitch forms of the fuel comprises one or more of a pastille, a briquette, or a flake.

5. A method of utilizing a petroleum pitch fuel with a recyclable powder coating, the method comprising:

applying a recyclable powder ash coating positioned to coat an outer surface of a plurality of selected petroleum pitch forms and at least partially penetrate the outer surface of the petroleum pitch forms during solidification, thereby to produce a penetrated ash coated petroleum pitch form, the penetrated ash coated petroleum pitch form also including a solvent deasphalted petroleum pitch;

providing the penetrated ash coated petroleum pitch form as a combustion fuel;

combusting the penetrated ash coated petroleum pitch form either singly or in combination with coal;

reclaiming the recyclable powder ash coating as a reclaimed ash; and

applying the reclaimed ash as the recyclable powder ash coating to the outer surface of a plurality of selected petroleum pitch forms, thereby to produce less total ash when combusting recyclable powder coated petroleum pitch fuel, the recyclable powder ash coating comprising one or more of a recycled ash, a recycled waste ash, a reclaimed ash or a coal ash.

6. The method of claim 5 , wherein the petroleum pitch forms of the fuel comprise one or more of a pastille, a briquette, or a flake.

7. A method of utilizing a petroleum pitch fuel with a recyclable powder coating, the method comprising:

applying a recyclable powder ash coating positioned to coat an outer surface of a plurality of selected petroleum pitch forms and at least partially penetrate the outer surface of the petroleum pitch forms during solidification, thereby to produce a penetrated ash coated petroleum pitch form, each of the selected petroleum pitch forms of the fuel comprises one or more of a pastille, a briquette, or a flake;

providing the penetrated ash coated petroleum pitch form as a combustion fuel;

combusting the penetrated ash coated petroleum pitch form either singly or in combination with coal;

reclaiming the recyclable powder ash coating as a reclaimed ash; and

applying the reclaimed ash as the recyclable powder ash coating to the outer surface of a plurality of selected petroleum pitch forms, thereby to produce less total ash when combusting recyclable powder coated petroleum pitch fuel, the recyclable powder ash coating comprises one or more of a recycled ash, a powdered ash, a recycled waste ash, a reclaimed ash, or a coal ash.
