Abstract: The inventive technology includes methods and apparatus for the generation and application of segregated catalytic additives for the pre-combustion treatment of carbonaceous fuel and/or feedstocks. The application of such segregated additives results in the reduction of environmentally harmful emissions during combustion as well as gasification processes. Specifically, pre-combustion treatment of carbonaceous materials with the inventive additives results in the reduction of NOx and/or mercury emissions by least 20% and 40% respectively.

Abstract: Coal particles to be processed into compressed articles are impregnated with a substance before being mixed with a binder system containing water and finally being processed into compressed articles.
Abstract: The invention relates to a method for producing shaped, activated charcoal. According to the method, after being ground, carbon-bearing material, or a mixture of several carbon-bearing materials are rendered homogenous with a binding agent which contains water, or a mixture of several binding agents, at least one of which contains water. The mixture of carbon-bearing material and binding agent is then formed into shaped bodies. According to the invention, in order to consolidate the grain formation, these are dried until they exhibit a maximum total water content of 3% by wt. in relation to the shaped body. The shaped bodies which have been formed and dried in this manner are then subjected to a carbonization and subsequently a gas activation process.

Abstract: Binder compositions for converting coal waste into fuel including a distillable petroleum hydrocarbon emulsified with a surfactant and water are provided. The invention also includes methods for making the binder compositions. The methods include blending a distillable petroleum hydrocarbon petroleum hydrocarbon with water and a surfactant. In another aspect, a fuel product is provided which includes the reaction product of carbonaceous fine particles and a binder composition of this invention. The binder composition is provided in an amount necessary to increase the hydrophobic characteristics of the carbonaceous fine particles and bring about a statistically significant change in their chemistry. In one embodiment the binder composition is present in an amount between about 1.5 percent and about 4.0 percent of the total weight. Methods are also provided for making fuel from fine carbonaceous materials, which include exposing the carbonaceous materials to a binder composition of this invention.
