  • Patent number: 6902589
    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.

  • Patent number: 6887282
    Abstract: A chemical change agent containing water, tall oil, glycerides, and surfactants is used to create synthetic fuels. An alternate composition contains water, glycerides, and surfactants. The chemical change agent is formed by heating the tall oil; combining water, fatty acids, and surfactant; and adding the heated tall oil and the water, fatty acid, and surfactant to form an emulsion. The synthetic fuel contains coal and the chemical change agent. The synthetic fuel is formed by mixing coal with the chemical change agent and pressing the two components into a briquette or other suitable treatment to create a finished product.

  • Patent number: 5916826
    Abstract: A coal agglomerate is produced by the combination of coal fines with a binder obtained by the direct liquefaction of biomass material. The direct liquefaction is carried out in the absence of oxygen at typical temperatures between about 450 and 700.degree. F. and typical pressures between 200 and 3,000 psi, according to known liquefaction processes. The liquefied bio-binder base is mixed with additives, if desired, such as fast pyrolysis tars and petroleum asphalt, in order to modify its characteristics to meet specific needs of particular applications, and the resulting mixture is sprayed on coal fines preheated to at least 250.degree. F. and allowed to react at about 300-400.degree. F. Combustible extenders and fillers; reinforcing fibers; and cross-linking agents may be mixed with the coal prior to combination with the binder to provide additional specific properties to the mixture. The resulting well mixed mass is then pelletized by the application of pressure in conventional equipment.
