ABSTRACT:
Disclosed is a pelletized fuel composition comprising coal fines in an amount of from 60% to 80% by weight, paper making sludge in an amount of from 10% to 30% by weight, and a shredded polymeric material in an amount of from 0.5% to 15% by weight. Surprisingly and unexpectantly, a high percentage of correctly sized pellets having a desired degree of hardness and structural integrity result without the necessity of a binder, the use of very high pressures or drying the completed pellets by heating at elevated temperatures. A method of manufacturing the fuel composition involving pelletizing at a pressure of from about 1,000 psig to about 4,000 psig is also disclosed.
