Un método para preparar una composición de combustible incluye colocar carbón que tiene un contenido de calor entre aproximadamente 3,000 BTU/lb y aproximadamente 9,000 BTU/lb y un contenido de humedad entre aproximadamente 20% en peso y aproximadamente 60% en peso en un recipiente. El carbón se expone al calor y a una presión menor que la presión atmosférica dentro del recipiente, reduciendo de este modo el carbón, de modo que un tamaño de partícula primaria promedio del carbón es menor de 1 milímetro. Se introduce un aglutinante al recipiente, de modo que el carbón se combina con el aglutinante para producir una mezcla. La mezcla está formada para producir una composición de combustible. A method of preparing a fuel composition includes placing coal having a heat content between about 3,000 BTU/lb and about 9,000 BTU/lb and a moisture content between about 20 wt % and about 60 wt % in a vessel. The coal is exposed to heat and a pressure less than atmospheric pressure within the vessel, thereby reducing the coal, such that an average primary particle size of the coal is less than 1 millimeter. A binder is introduced to the vessel, such that the coal combines with the binder to yield a mixture. The mixture is shaped to yield a fuel composition.
