A method to create a natural charcoal briquette is described herein. A wood material is collected and impurities are removed from the wood material. The wood material is dried at a temperature in a range of approximately 150° C. to approximately 200° C. to reach a moisture level in a range of approximately 3.7% to approximately 5.0%. The dried wood material is compressed in a shaped mold at approximately 300° C. and under 40 tons of pressure to form a charcoal briquette. The charcoal briquette is carbonized at a temperature in a range of approximately 700° C. to approximately 800° C. in a range of approximately 14 days to approximately 17 days. The charcoal briquette is then cooled for approximately 2 days prior to use or packaging.

A method for preparing a fuel pellet/briquette, the method comprising: a) providing cotton gin trash as feed material; b) heating the feed material to a temperature of at least 75° C.; c) compressing the heated feed materials without addition of a binding agent at a pressure to form the fuel pellet/briquette.

The production of steam-cracked biomass in the form of black pellets in the field of solid biofuels. More particularly, the present disclosure relates to the production of black pellets from a heterogeneous biomass. The aim of the present disclosure is to produce black pellets having good mechanical strength, good water resistance and an increased calorific value.

The invention relates to a method for solidifying a floating fat and oil in a food waste water, the method being capable of solidifying floating oil by uniformly mixing and aging the floating oil having a high content of water generated during the process of treating high concentration waste water generated during a food waste treatment process or generated from a food company, slaughterhouse and the like.

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.

A system and method for torrefying a combination of biomass and biochar colloidal dispersion is provided.

A biomass solid fuel manufacturing method, including: a heating step of carbonizing a biomass molded body formed by molding raw material biomass, in an external heating type rotary kiln, in which the rotary kiln includes a non-heating zone that is provided on an upstream side of a kiln body and is not provided with a heating unit on an outer circumference, the non-heating zone includes a spiral blade on an inner circumferential surface, and in the heating step, the biomass molded body is introduced to the non-heating zone of the kiln body.

A system for processing a stream including fuel oil includes an atmospheric flash column for receiving the stream as feedstock and separate the stream into an atmospheric flash distillate stream and an atmospheric flash residue stream. The system includes a vacuum flash column for receiving the atmospheric flash residue stream and separating the atmospheric flash residue stream into a vacuum flash distillate stream, a vacuum flash residue stream, and a vacuum gas oil stream. The system includes a first hydrocracking unit for receiving and processing at least a portion of the vacuum flash residue stream to produce an intermediate stream and a slurry. The system includes a second hydrocracking unit for receiving and processing the vacuum gas oil stream and the intermediate stream to produce a naphtha product and a light ends product. The system includes a pelletization unit for receiving and processing the slurry to produce a pelletized product.

A method of preparing a fuel composition includes placing coal having a heat content between about 3,000 BTU/lb and about 9,000 BTU/lb and a moisture content between about 20 wt % and about 60 wt % in a vessel. The coal is exposed to heat and a pressure less than atmospheric pressure within the vessel, thereby reducing the coal, such that an average primary particle size of the coal is less than 1 millimeter. A binder is introduced to the vessel, such that the coal combines with the binder to yield a mixture. The mixture is shaped to yield a fuel composition.

Systems and methods of producing a solid fuel composition are disclosed. In particular, systems and methods for producing a solid fuel composition by heating and mixing a solid waste mixture to a maximum temperature sufficient to melt the mixed plastics within the solid waste mixture is disclosed.
