摘要： A biofuel product having constituents selected from the group including fat, oil and/or grease components. A container is formed of a biodegradable material having a multiplicity of openings of a size and shape adapted for allowing the fat, oil and/or grease components to pass through the openings to an interior area of the container. An absorbent capture material is positioned in the container and holds a quantity of the fat, oil and/or grease. The container, capture material and fat, oil and/or grease collectively comprise the biofuel product.

摘要： It is disclosed a combustible article of manufacture comprising a treated lignin composition and a combustible support, wherein the treated lignin composition is attached to at least a portion of an external surface of the combustible support with a force greater than the force of gravity relative to the treated lignin composition. The treated lignin composition comprises solid lignin and has a moisture content in the range of 35% to 80% percent by weight. The combustible support is preferably a hardwood chip, but it may be also softwood chips, coal, coke, and shredded tires.
It is also disclosed a fuel composition comprising a plurality of the combustible article.-

摘要： A method for processing lignocellulose materials comprising the steps of hydrothermal treatment of the material with saturated or superheated steam in a hydrothermal pressure vessel, wherein the steam is provided by means of a steam boiler. The treatment is performed at a pressure of 5-30 bars, and at a temperature of 160-240° C. for a duration of 1-20 minutes. The method further comprises discharging hydrothermally treated lignocellulose material and steam from the pressure vessel by means of rapid pressure reduction, separating the steam and vapours released from the lignocellulose material, and burning the vapours together with additional fuel and combustion air in the furnace of said steam boiler. Furthermore, a corresponding system is provided.

摘要： This invention provides processes and systems for converting biomass into high-carbon biogenic reagents that are suitable for a variety of commercial applications. Some embodiments employ pyrolysis in the presence of an inert gas to generate hot pyrolyzed solids, condensable vapors, and non-condensable gases, followed by separation of vapors and gases, and cooling of the hot pyrolyzed solids in the presence of the inert gas. Additives may be introduced during processing or combined with the reagent, or both. The biogenic reagent may include at least 70 wt %, 80 wt %, 90 wt %, 95 wt %, or more total carbon on a dry basis. The biogenic reagent may have an energy content of at least 12,000 Btu/lb, 13,000 Btu/lb, 14,000 Btu/lb, or 14,500 Btu/lb on a dry basis. The biogenic reagent may be formed into fine powders, or structural objects. The structural objects may have a structure and/or strength that derive from the feedstock, heat rate, and additives.

摘要： A method of preparing agglomerates of ultra-fine coal particles includes mixing a film forming agglomeration aid (FFAA) with a quantity of ultra-fine coal particles to form ultra-fine coal particles coated with the FFAA. The FFAA has a lower surface energy relative to a surface of the ultra-fine coal particles. The FFAA is mixed with the ultra-fine coal particles in an amount less than 3% by weight of the ultra-fine coal particles on a dry basis. Agglomerates of the ultra-fine coal particles coated with the film forming agglomeration aid are formed using vibration, pelleting, and/or briquetting. The agglomerates have a size of at least 2 mm. The ultra-fine coal particles have a particle size less than 100 μm. The agglomerate has a tumbler test friability less than 3%. The drop shatter friability is also less than 3%.

摘要： A process for upgrading of a coal product is provided. The process comprising the steps of: (i) providing a purified coal composition, wherein the composition is in the form of solid particles, and wherein at least about 90% by volume (% vol) of the solid particles are no greater than about 500 μm in diameter; and (ii) combining the purified coal composition with a solid coal feedstock, in order to create a combined solid-solid blend upgraded coal product. Further a process for preparation of a purified coal product is provided. The process comprising the steps of: obtaining a starting material that comprises coal; subjecting the starting material to at least one fine grinding stage so as to reduce the starting material to a particulate composition in which substantially all of the particles are no more than 500 microns (μm) in diameter; exposing the particulate composition to at least one froth flotation stage so as to separate hydrocarbonaceous material comprised within the particulate composition from mineral matter, wherein during the at least one froth flotation stage the hydrocarbonaceous material is associated with froth produced and separated from the at least one froth flotation stage; washing the froth separated from the at least one froth flotation stage with water to release the hydrocarbonaceous material; and subjecting the hydrocarbonaceous material to at least one dewatering stage so as to obtain a particulate purified coal product that has an ash content of less than 12% m, a water content of less than 25% m and wherein the particles comprised within the particulate purified coal product have a d90 of less than 00 μm. Products, such as pelletized or briquetted coal, comprising purified coal material obtainable via the described processes are also provided.

摘要： The present technology provides compositions that include at least about 98 weight percent (“wt %”) n-paraffins which, among other surprising features, may be suitable for use as a diesel fuel, an aviation fuel, a jet fuel blendstock, a blendstock to reduce the cloud point of a diesel fuel, a fuel for portable heaters, and/or as a charcoal lighter fluid. The composition includes at least about 98 wt % C7-C12 n-paraffins, where at least about 10 wt % of composition includes n-decane, at least about 20 wt % of the composition includes n-dodecane, and at least about 75 wt % of the composition includes even carbon number paraffins. The composition also includes less about 0.1 wt % oxygenates and less than about 0.1 wt % aromatics. The composition may be produced by a process that includes hydrotreating a biorenewable feedstock comprising at least one of palm kernel oil, coconut oil, babassu oil, microbial oil, or algal oil.
