Structured composite wood pellets comprising wood pellets with a coating at least partially covering the wood pellets, where the coating reduces the generation of dust/fines of the wood pellet upon impact and/or abrasion. The coating may comprise crude tall oil, distilled tall oil, tall oil pitch, tall oil fatty acids, tall oil heads, non-food use sustainable wax, or a combination thereof. The coating may be located at the surface and/or subsurface of the wood pellets rather than throughout, and may be applied at a rate of less than 1 wt. % of the wood pellets.

Methods and compositions for treating coal are provided. A nitroxyl radical compound is added to the coal in order to inhibit coal autooxidation. Additionally, the nitroxyl radical compound can be conjointly used with conventional dust control agents, in order to suppress fugitive coal dust dissemination. In those cases in which foamed treatment is desired to treat coal dust, the nitroxyl radical compound can be conjointly used in the foamable compositions, along with a variety of foam building surfactants such as the amphoteric, nonionic and anionic surfactants.

A pipeline transportation method of coal is provided. The coal is pulverized and then subjected to a waterproofing treatment, so that a time needed for precipitating the pulverized coal in water is longer than a time needed for transporting the pulverized coal by flowing water to a destination. The waterproof pulverized coal is transported by water through a pipeline. After reaching the destination, the waterproof pulverized coal can be separated from the water in a static pool, collected by a cyclone separator, and then stored in a warehouse.

A method for producing charcoal particles or pellets which use different additives as binders for the biochar pellets. The method includes producing a mixture with charcoal and additives selected from nanocrystalline cellulose, nanocrystalline fibrils, bentonite, and polyvinyl acetate. The mixture is created by mixing one or more of the additives with charcoal or bentonite. The mixture is then processed in a pelletizer device. While processing, the surface of the mixture is sprayed with a liquid. Once turned into pellets by way of the pelletizer device, the resulting pellets are then dried by applying heat to the pellets. The liquid can be water or a solution of water and sodium borate.

A process for torrefaction of biomass is provided in which biomass are passed into a fluidized bed or a non-fluidized bed reactor and heated to a predetermined temperature in an oxidizing environment. The dried biomass is then fed to a cooler where the temperature of the product is reduced to approximately 100 degrees Fahrenheit.

A method for manufacturing dried combustible material includes: a mixing step of mixing a number of particles made of combustible material containing moisture and a dehydrating liquid made of an emulsion containing synthetic resin to form a mixture in which surfaces of the particles are made contact with the dehydrating liquid; and a drying step of forming a synthetic resin coating made of the dehydrating liquid dried on the surfaces of the particles and evaporating the moisture of the particles, to form coated particles including the particles having a reduced moisture content percentage and the synthetic resin coating that covers the surfaces of the particles, and produce dried combustible material made up of the coated particles.
