SOLIDIFICATION TECHNIQUES FOR LOW SOFTENING POINT PETROLEUM PITCH
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.
