    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: Systems and methods for production for consistently sized and shaped petroleum coke from vacuum residue, one method including supplying processed vacuum residue to an extruder; heating the processed vacuum residue throughout a horizontal profile of the extruder from an inlet to an outlet of the extruder; venting hydrocarbon off-gases from the extruder along the horizontal profile of the extruder from the inlet to the outlet of the extruder; and cutting consistently sized and shaped petroleum coke at the outlet of the extruder.

    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 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 %.
