摘要： The invention provides low-cost, non-thermal methods to transform and beneficiate bulk materials, including low rank coals such as peat, lignite, brown coal, subbituminous coal, other carbonaceous solids or derived feedstock. High pressure compaction and comminution processes are linked to transform the solid materials by eliminating interstitial, capillary, pores, or other voids that are present in the materials and that may contain liquid, air or gases that are detrimental to the quality and performance of the bulk materials, thereby beneficiating the bulk products to provide premium feedstock for industrial or commercial uses, such as electric power generation, gasification, liquefaction, and carbon activation. The handling characteristics, dust mitigation aspects and combustion emissions of the products may also be improved.

摘要： A process and system is provided for briquetting particulate matter such as moisture-containing bituminous and sub-bituminous coal. This process includes partially drying the particulate matter and feeding, the partially dried particulate matter to a briquetting apparatus under conditions such that water vapor is released from the particulate matter during feeding. The particulate matter is passed through briquette forming rollers to form briquettes. The released water vapor substantially displaces or prevents the ingress of a large proportion of other gaseous components from the atmosphere surrounding and/or intermixed with the particulate matter. The particulate matter that is fed to the briquetting apparatus is surrounded by and intermixed with a gaseous component containing 70 to 100% by volume of water vapor at the point where it enters the briquette-forming part of the briquetting apparatus.

摘要： A method and composition for suppressing coal dust include a metal-containing compound, such as an organo-manganese, that provides the additional benefit of being a combustion improver. The organometallic compound is mixed with any appropriate dust suppressant liquid. The organometallic compound may include methylcyclopentadienyl manganese tricarbonyl.

摘要： The present invention discloses methods to reduce dusting in bulk materials, such as coal. The method includes mixing with the bulk material either a fraction of the bulk material having an electrostatic charge opposite that of the remainder of the bulk material or a heterologous charge control agent having an electrostatic charge opposite that of the bulk material. The attractive forces between the opposite electrostatic charges agglomerate dust particles to larger particles that quickly settle to control dusting. Also disclosed are materials produced by the methods described above.

摘要： A method for producing modified coal using coal of a low grade comprising: adding water for preventing any dust generation to the dewatered coal; an addition amount of the water is adjusted for a water content rate of the water-added coal to be 6% by mass or more to 16% by mass or less; agglomerating the water-added coal; slowly oxidizing the agglomerated coal; and crushing the oxidized coal.

摘要： A high-energy water-resistant pellet of at least 75% torrefied wood and the remainder a binder comprising from about 2% to about 20% by total weight of the pellet. The binder is a two-component system—a plasticizer, such as tall oil pitch, rosin, fatty acid, vegetable oils, animal oils and corn protein—preferably from 3% to about 20% of the binder, and lignin from about 80-97% of the binder. A durable, low dust white wood energy pellet is also provided using the same two-component binders.

摘要： A coal processing mill incorporates integral systems for coarse coal dewatering, grinding, injection of a peptizing agent into the ground coal stream before it enters an agitation zone (where the peptization process takes place), passing the treated coal and the peptized clay and ash through a separating valve and passing the separated coal on to final drying. In other embodiments, ash and pyrites (of much higher density than coal) are separated from coal and the coal can then be fired.

摘要： Methods are provided for controlling fugitive dust emissions from a variety of granular or particulate solids materials such as coal dust. A first treatment of cationic polymer or cationic copolymer is applied to the dust. The dust is then loaded onto an open bed rail car or the like. A topping treatment comprising an aqueous dilute polymer solution or polymer latex emulsion or dispersion is applied to the exposed coal layer in the rail car.
