Process for beneficiating and cleaning biomass
A process for cleaning and beneficiating biomass is described which may allow removal of entrained salts and light volatiles from biomass materials. The process may also minimize energy use through capturing steam and flue gases for re-use. The process may generally comprise the following steps: prewashing and/or preheating a biomass, pressurizing the biomass in a steam explosion vessel, rapidly depressurizing the steam explosion vessel, releasing the steam from the steam explosion vessel entrained with fine lignin-enriched particles into a cyclone-type gas expansion vessel, routing the steam from the gas expansion vessel to the input hopper, subjecting the biomass to a second washing step, mechanically removing a portion of the water from the biomass, and evaporatively heating the biomass.
PROCESS FOR FORMING A FUEL PELLET
The present invention relates to a process for forming a fuel pellet, based on using a particular formula for making the fuel pellets. The process for forming a fuel pellet comprising of the following steps:
providing a particulate carbonaceous material having a particle size of <1 mm;
admixing the particulate carbonaceous material with a polysaccharide or a polyvinyl alcohol binder, and a crosslinker;
shaping the so-formed mixture to provide the fuel pellet.
FORMULA AND PROCESS FOR MAKING FUEL PELLETS
The present invention relates to a pelletisable formula, and a process for using the formula for making fuel pellets. The pelletisable formula comprises a particulate carbonaceous material such as coal dust or coal fines of particle size <1 mm, a polysaccharide or a polyvinyl alcohol binder, and a crosslinker such as zirconium carbonate or sodium borate.
SYSTEMS, METHODS AND TECHNIQUES FOR TORREFACTION
A system for torrefaction of waste material comprising biogenic material and plastic material may comprise a material pre-processing system, a heating and compaction unit, a reactor system comprising a reaction portion and an extrusion portion, and a cutting unit adjacent an outlet of the reactor system.

HIGH-CARBON BIOGENIC REAGENTS AND USES THEREOF
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.
METHOD OF PRODUCING A DRAG REDUCER
A method for preparation of a reagent for reducing hydrodynamic drag of a turbulent flow of liquid hydrocarbons in pipelines, characterized by a high polymer content of at least 75 wt %, including mixing a 0.1-1.5 mm polymer reducing the hydrodynamic drag of a turbulent flow of liquid hydrocarbons with polymer non-solving solvents. The prepared product is a commodity form of the reagent with a high polymer content of at least 75 wt % used to reduce the hydrodynamic drag of the flow of liquid hydrocarbons in pipelines. The product prepared according to the described method is injected into the flow of hydrocarbon fluid transported through the pipeline using the injection apparatus that mechanically moves the product using a screw auger or screw feeder.

Production of renewable bio-gasoline
A process and system for separating bio-gasoline, bio-diesel and bio-fuel oil fractions from a bio-oil, and for producing a renewable gasoline including at least in part the bio-gasoline fraction, is provided. The process comprises separating bio-oil into a bio-gasoline fraction and a heavy fraction based on their boiling points. At least a portion of the bio-gasoline fraction is directly blended with a petroleum-derived gasoline, without any prior hydrotreatment, to thereby provide a renewable gasoline composition.
METHOD AND INDUSTRIAL PLANT FOR SEPERATING A WASTE MATERIAL
A method and an industrial plant for separating a waste material comprises at least one metal and at least one organic material. A separated fraction of the waste material is provisioned which is isolated from the waste material in the course of a mechanical preparation operation. The separated fraction comprises briquettes produced from the waste material, and optionally a coarse fraction of the waste material or of another waste material. A reactor is charged with the separated fraction and gas containing oxygen is introduced into the reactor and the separated fraction is combusted in an incomplete combustion process. The separated fraction is melted into a liquid slag phase and into a liquid metal-containing phase. The slag phase and/or the metal-containing phase are poured off from the reactor.
