Fuel composition

A fuel composition, comprising:

• less than about 10% down to about 3% by weight water;
• greater than about 35% by weight solids, said solids comprising inorganic solids and combustible organic solids that are insoluble in methylene chloride;
• at least about about 30% by weight of liquid hydrocarbons;
• the composition having a minimum heat value of at least about 7,000 BTU/lb. and viscosity such that said composition is a pumpable fluid at ambient temperature, said solids and said liquid hydrocarbons being obtained from the same refinery waste stream containing liquid hydrocarbons, water and said solids whereby all of the heat value of said composition is derived from components initially present in said waste stream.

A fuel composition derived from a waste stream, consisting essentially of:

• water;
• greater than about 35% by weight solids, said solids being obtained from a refinery waste stream containing liquid hydrocarbons, water and solids, such that at least about 12 percent by weight of the fuel composition comprises inorganic solids;
• and
• at least about 30% by weight of liquid hydrocarbons;
• the composition having a minimum heat value of at least about 7,000 BTU/lb. and having a viscosity wherein the composition is a pumpable fluid at ambient temperature;
• with the proviso that no more than about ten percent by weight of water is present.
