Abstract: A method of manufacturing a coal product having reduced sulfur emissions including the steps of grinding coal into a powder form having a desired particle size; blending the ground coal with hydrated lime; adding water to the blend so as to have a moisture content of between 10 and 30 weight percent and drying the water-added blend so as to have a desired reduced moisture content. The desired reduced moisture content is less than 1% of the total weight of the coal powder and the hydrated lime. The step of drying includes heating the water-added blend to a temperature of between 300 and 400° F. in an externally heated oven. Waste heat form a power plant can be used so as to head the blend.

Abstract: A method of preparing a high heating value fuel product having the steps of blending a hydrocarbon-containing material with a dried sewage sludge, mixing a monomeric polyalcohol to the blend of the hydrocarbon-containing material and the dried sewage sludge, introducing a pozzolanic agent to the mixture, and forming the mixture into a form suitable for handling. The hydrocarbon-containing material is a waste material having a heating value of greater than 7,000 BTU. The monomeric polyalcohol is a chemical selected from the group of triethylene glycol, diethylene glycol, and glycerine propylene glycol. The pozzolantc agent is either lime fly ash, kiln dust, or other lime-containing product.

Abstract: The process for immobilizing a hazardous waste containing heavy metals comprises the steps of pretreating the waste by adding a sulfide to the hazardous waste so as to generate the sulfides of the heavy metals from the hazardous waste, mixing a chemical reagent with the pretreated waste, and blending the mixture of the chemical reagent and the pretreated waste with a pozzolanic material. The chemical reagent contains a mixture of a retarder and an accelerator. This process further comprises the step of mixing a neutralizing reagent with the hazardous waste so as to cause the hazardous waste to have a pH of between 5 and 14. The neutralizing reagent is an alkaline material, preferably lime, hydrated lime, or calcium hydroxide. The sulfide is either sodium hydrosulfide or sodium sulfide.
