Abstract:
The invention provides a process for producing cement, the process comprising providing heat to a cement manufacturing process using a secondary fuel, wherein the secondary fuel comprises cellulose and plastic and is in the form of pellets of a size between about 3-25 mm thickness, having a calorific value of about 16 GJ/ton or more, and wherein said secondary fuel is supplied at a place between the kiln inlet and the first cyclone, wherein after formation of the cement clinker, the cement clinker is cooled and milled to cement powder. Preferably, the secondary fuel is supplied to the riser pipe or to a pre-kiln combustion chamber. Generally, the secondary fuel is provided at a place which allows the pellets to burn before coming in contact with the cement materials in the kiln, while it also does not rise into the cyclone, thereby preventing blocking of the cyclones.

Abstract:
The invention relates to a process for firing an industrial furnace, in particular for electricity generation, wherein coal or cokes together with a secondary fuel comprising cellulose and plastic, in the form of pellets of a size larger than about 3 mm thickness, and having a caloric value of about 16 GJ/ton or more is ground to a powder wherein about 95 wt% or more has a particle size smaller than 2 mm and wherein the d50 of the particle size distribution is between about 5 and about 100 µm, wherein the powder is injected in the flame of the furnace. In this process the grinding is performed in a roller mill or ball mill, and the amount of pellets used together with the coals preferably is about 3 wt% or more, relative to the coal.
Abstract:
A carbonaceous compact is provided by the present disclosure that includes a body having a partially or fully carbonaceous biomass composition and an adhesive additive. The adhesive additive includes a starch and a hydroxide. The porous nature of the carbonaceous material provides means for nutrient retention or filtering means. Carbon is activated through chemical or thermal reaction from pyrolyzed wood/nut. A method of processing the carbonaceous compact is also provided that comprises combining a composition of combustible biomass materials, drying the composition, adding the adhesive additive, adding any further additivies, such as silica and beneficial bacteria. The composite biomass is processed into a shapeform, and then the shapeform is partitioned into individual pieces that are compatible with existing handling methods. In one form the processing is formed at about 500°C so that biochar is formed, while processing above 518°C - 572°C carbon is formed with subsequent activation.
Abstract:
A method for the torrefaction of biomass comprises receiving biomass having a given moisture content. The biomass is heated in a generally inert environment by indirect contact. The biomass is subsequently torrefied by exposing the biomass to a flow of combustion gases in the generally inert environment. The biomass is outlet with a reduced moisture content.
Abstract:
A method of processing a biomass fuel compact is provided by the present disclosure that includes comprising combining a composition of combustible biomass materials, comminuting the composition of biomass materials, drying the comminuted composition of biomass materials, and adding an adhesive to the biomass materials, the adhesive comprising a starch and a hydroxide. Further additives are also provided, which include a silicate, a viscosity agent, a preservative, and a BTU additive. The composite biomass is processed into a shapeform, and then the shapeform is partitioned into individual pieces that are compatible with existing powerplants. In one form, the processing is performed at lower temperatures such that an endothermic reaction of the biomass materials and adhesive results.
