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

exact text as granted — not AI-modified
I claim: 
     
         1 . A reclaimed waste product which has a solid, particulate consistency at ambient temperature comprising a composite of petroleum pitch and a powder coating. 
     
     
         2 . The product of  claim 1  wherein the pitch is lower softening point petroleum pitch. 
     
     
         3 . The product of  claim 1  wherein the pitch is solvent deasphalted (SDA) petroleum pitch. 
     
     
         4 . The product of  claim 1  wherein the powder coating is pulverized coal. 
     
     
         5 . The product of  claim 1  wherein the powder coating is recycled coal ash. 
     
     
         6 . The product of  claim 1  wherein the powder coating penetrates the surface of the pitch. 
     
     
         7 . The product of  claim 1  wherein the product is fuel. 
     
     
         8 . The product of  claim 1  wherein the product is in the form of pastilles. 
     
     
         9 . The product of  claim 1  wherein the product is in the form of briquets. 
     
     
         10 . A method for producing a reclaimed waste product which has a solid, particulate consistency at ambient temperature comprising the steps of:
 cooling petroleum pitch;   coating the cooling pitch with a powder coating during the step of cooling; and   allowing the powder coating to penetrate more deeply into the pitch during the step of cooling.   
     
     
         11 . The method of  claim 10  wherein the pitch is lower softening point petroleum pitch. 
     
     
         12 . The method of  claim 10  wherein the pitch is solvent deasphalted (SDA) petroleum pitch. 
     
     
         13 . The method of  claim 10  wherein the powder coating is pulverized coal. 
     
     
         14 . The method of  claim 10  wherein the powder coating is recycled coal ash. 
     
     
         15 . The method of  claim 10  wherein the powder coating penetrates the surface of the pitch.
