Abstract: The invention relates to a method to produce powdery alternative fuel by milling pellets, which pellets are produced by: (i) providing waste material comprising one or more thermoplastic material(s) of more than 40%, based on the total dry weight of the waste and one or more cellulosic material(s) of more than 30%, based on the total dry weight of the waste, wherein the waste has a particle size distribution with more than 80 wt % larger than 5 mm and more than 95 wt % smaller than 60 mm, having a water content of about 8 wt % or less; (ii) subjecting the waste material through a pelletiser with holes between 4-8 mm, and a length ratio of more than 10, such that the output temperature is about 85° C. or lower, (iii) subjecting the pellets through a second pelletiser with holes between 2 and 8 mm, and a length ratio of more than 14, such that the output temperature is about 110° C. or higher; (iv) to provide pellets, (v) and the pellets are cooled to a temperature of about 30° C. or lower. The powdery alternative fuel can be transported in bulk and through blowing lines.

Abstract: This document describes methods for pretreating coal to create either a dried coal or a char product that is stable in the outdoor environment and is more efficient as a feedstock for gasification or other processes than the original coal. Embodiments of the methods include pulverizing and pelletizing the coal, and pretreating the coal pellets to obtain a stable pellet of either dried coal or a stable pellet of chared coal (coal char). The pellets created by the described methods have undergone deoxygenation and carbonization improving their handling and storage properties and, in some cases, energy density. Pore structures within the pellets are stabilized physically and chemically so that the uptake of moisture into dry coal, that leads to internal heat generation, is greatly reduced. Chars are also, therefore, stable against transitions from a dry state to a wet state and less prone to self-ignition.

Abstract: A method is disclosed for producing a mechanically stable, energy dense and water-resistant biomass product. By utilizing a unique two-step heating process in combination with mechanical compression, the resulting biomass product retains its physical shape and strength after immersion in ambient water for many hours. The treatment is effective for a variety of cellulosic biomass materials including forest slash wood.

Abstract: An additive used in the production of wood pellets to increase throughput. The additive may be applied as a booster to wood prior to forming the wood into pellets. The booster may comprise 30% to 100% tall oil pitch and 70% to 0% tall oil head and may be applied at a rate of 0.01 to 2 wt. % of the wood.

Abstract: A process for making a renewable processed biochar pellet composition made with a pelletizing sub-system followed with a heating sub-system from a processed organic-carbon-containing feedstock made with a beneficiation sub-system is described. Renewable biomass feedstock passed through a beneficiation sub-system to reduce water content to below at least 20 wt % and an intracellular water-soluble salt reduction of at least 60% from that of unprocessed organic-carbon-containing feedstock on a dry basis. The processed feedstock is introduced into a pelletizing sub-system and then into a heating sub-system to result in renewable processed biochar pellets having an energy density of at least 21 MMBTU/ton (24 GJ/MT), a water content of less than 10 wt %, and an intracellular water-soluble salt content that is decreased by at least 60 wt % on a dry basis for the processed organic-carbon-containing feedstock from that of the unprocessed organic-carbon-containing feedstock.

Abstract: A processed biomass/coal blended compact aggregate composition made with a blending sub-system from a processed organic-carbon-containing feedstock made with a beneficiation sub-system and low energy coal is described. Renewable biomass feedstock passed through a beneficiation sub-system to produce a processed biomass with an energy density of at least 17 MMBTU/ton (19 GJ/MT), a water content of below at least 20 wt % and an intracellular water-soluble salt that is at least 60% below that of unprocessed organic-carbon-containing feedstock on a dry basis. Low energy un-cleaned coal is sized and passed through a coal cleaning sub-system to result in cleaned low energy coal having an energy density of less than 21 MMBTU/ton (24 GJ/MT) and a content of sulfur that is at least 50 wt % below that of the content of sulfur in the coal before it passed through the coal cleaning sub-system. The processed feedstock is sized and blended with the cleaned low energy coal in a blending sub-system to form a blended aggregate that comprises at least 10 wt % of the cleaned low energy coal and at least 10 wt % of the processed biomass.

Abstract: A method for storing upgraded coal, which is economical and whereby it becomes possible to prevent the spontaneous ignition of piles; and grain-size-controlled coal which rarely undergoes spontaneous ignition during storage. The method for storing upgraded coal includes piling up granular coal containing upgraded coal, wherein the content of grains each having a grain size of 10 mm or less in the coal is 50 mass % or more. It is preferred that the content of grains each having a grain size of 1 mm or less is 25 mass % or more and the content of grains each having a grain size of 0.15 mm or less is 7 mass % or more in the coal.

Abstract: A lubricity additive for fuels with sulphur content of not more than 0.05 wt % is described herein. The lubricity additive comprises a polyol ester or a mixture of polyol esters derived from C8-C18 saturated and/or unsaturated fatty acids. The polyol esters is produced by: i) esterification of a C8-C18 saturated or unsaturated fatty acids, or a mixture thereof, with a polyhydric alcohol; ii) transesterification of an oil or a mixture of oils, with fatty acid composition comprising C8-C18 saturated and/or unsaturated fatty acids, with a polyhydric alcohol. The preferred fatty acids are unsaturated C18 fatty acids, more particularly, oleic acid whereas the preferred polyhydric alcohol is neopolyol, more particularly, trimethylol propane and its isomers. A fuel composition comprising a major amount of fuel with sulphur content of not more than 0.05 wt % and a minor amount of the lubricity additive is also described herein. The amount of the lubricity additive is not more than 0.1 wt %.
