This disclosure pertains to the use of black liquors from kraft pulp mills as a source of catalysts for the thermochemical conversion of organic matter feedstocks to bio oils. More particularly, some embodiments pertain to integrated kraft pulp mill and thermochemical conversion systems, which include: a Kraft pulp mill comprising a digester for digesting a lignocellulosic material with white liquor to produce pulp and black liquors; a thermochemical conversion subsystem comprising: at least one mixing tank for combining pulping liquors received from the pulp mill with an organic matter feedstock and water to produce a reaction mixture; a reactor vessel for treating the reaction mixture received from the mixing tank at a reaction temperature and pressure suitable for conversion of all or a portion of the organic matter in the reaction mixture into a product mixture comprising a bioproduct and an aqueous stream containing both organic and inorganic compounds; and a depressurizer for depressurizing product mixture received from the reactor vessel; and one or more conveyors for conveying the pulping liquors from the pulp mill to the mixing tank.

A fire starter kit that includes a frame, a scratcher, a sparking road, and at least one fuel reservoir. The frame is having a first end, a second end, a middle region, a recess provided on the middle region, and a first slot provided along the first end, the second end and partially through the middle region. The scratcher removably mounted in the recess, wherein the scratcher is having at least one blade provided with a plurality of tooths. The sparking rod is removably mounted within the first slot, wherein the sparking rod is configured to produce sparks when scratched with the scratcher.

The present invention relates to a process for producing a solid biomass fuel, as well as a solid biomass fuel produced by said process. Additionally, the present invention relates to a combustion process comprising combusting said solid biomass fuel so as to produce energy.

The present invention relates to a process for producing a solid biomass fuel from rice husks either alone or in combination with other materials such as calliandra callothyrsus or wood, as well as a solid biomass fuel produced by said process. Additionally, the present invention relates to a combustion process comprising combusting said solid biomass fuel so as to produce energy.

Char fuels are described that result from a simple and efficient carbonization of cellulosic and/or lignin-containing materials, and can be provided as pellets, briquettes, or powders. Such char fuels show very low water absorption.

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.

The present invention relates to a method for producing agglomerates from a feedstock comprising at least one biomass stream, the method comprising the steps of: combining the feedstock with one or more binding reagents; and introducing the feedstock into an agglomeration apparatus in the presence of a polymerisation activator to produce the agglomerates.

Pellets and a process for producing pellets are disclosed. The process includes recovering spent coffee grounds from a coffee production facility. The coffee grounds are then subject to a drying process to remove moisture from the coffee grounds to form dried coffee grounds. A mixture of about 0.5-10% dried coffee grounds and wood material is then formed. The mixture is then compressed in a pellet mill to form wood pellets including about 0.5-10% coffee grounds. The coffee grounds in the wood material acts as a lubricant for the pelleting machinery and eliminate the need for other lubricants in the process.

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.
