In some variations, the invention provides a biocarbon composition comprising a low fixed carbon material with a fixed carbon concentration from 20 wt % to 55 wt %; a high fixed carbon material with a fixed carbon concentration from 50 wt % to 100 wt % (and higher than the fixed carbon concentration of the low fixed carbon material; from 0 to 30 wt % moisture; from 0 to 15 wt % ash; and from 0 to 20 wt % of one or more additives (such as a binder). Some variations provide a process for producing a biocarbon composition, the process comprising: pyrolyzing a first biomass-containing feedstock to generate a low fixed carbon material; separately pyrolyzing a second biomass-containing feedstock to generate a high fixed carbon material; blending the low fixed carbon material with the high fixed carbon material, thereby generating an intermediate material; optionally, blending one or more additives into the intermediate material; optionally, drying the intermediate material; and recovering a biocarbon composition containing the intermediate material or a thermally treated form thereof.

Some variations provide a process for producing biocarbon pellets, comprising: pyrolyzing a biomass-containing feedstock in a first pyrolysis reactor to generate a first biogenic reagent and a pyrolysis vapor; introducing the pyrolysis vapor to a separation unit, to generate a pyrolysis precipitate in liquid or solid form; contacting the first biogenic reagent with the pyrolysis precipitate, thereby generating an intermediate material; pelletizing the intermediate material, to generate intermediate pellets; optionally, drying the intermediate pellets; separately pyrolyzing the intermediate pellets in a second pyrolysis reactor to generate a second biogenic reagent and a pyrolysis off-gas; and recovering the second biogenic reagent as biocarbon pellets. Some variations provide a similar process that utilizes a carbon-containing condensed-matter material, which is not necessarily a pyrolysis precipitate. The disclosure provides improved processes for producing biocarbon compositions, especially with respect to carbon yield and biocarbon properties, such as reactivity.
Covered cavity kiln pyrolyzer
The invention presents a covered cavity kiln pyrolyzer with modulated means of rotation, to promote mixing and exposure of the biomass to heat, thereby allowing complete and efficient pyrolysis of biomass therein. The invention has a portal arrangement for simultaneous entry of fuel and air alongside the exit of emissions and flames to a separate hood structure. In addition to rotational modulation for mixing, the rotational capabilities of the kiln also permit the removal of processed charcoal when the portal is turned downward. The invention also has a system of internal prongs for mixing and sifting removal of char, as well as automated fuel delivery mechanisms and a system of openings to allow insertion of pipes and sensors into the kiln for monitoring and for additional delivery of reagents for better modulation and efficiency by a user during the pyrolyzation process.
SYSTEMS AND APPARATUS FOR PRODUCTION OF HIGH-CARBON BIOGENIC REAGENTS
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.

Clean, safe and efficient methods, systems, and processes for utilizing thermolysis methods to processes to convert various e-waste sources into Clean Fuel Gas and Char source are disclosed. The invention processes e-waste sources, such as for example whole circuit boards, to effectively shred and/or grind the waste source, and then process using thermolysis methods to destroy and/or separate halogen and other dangerous components to provide a Clean Fuel Gas and Char source, along with the ability to recover precious metals and other valuable components from the Char.
METHOD OF OXIDATION IN A MOLTEN SALT BATH
A method for reusing waste including organic components in a bath of molten salt including providing to a reactor, at least one salt or a mixture of salts including at least one alkali metal hydroxide, providing the waste to the reactor, heating the at least one salt or mixture of salts in the reactor at a temperature above the melting point of the salt. Thus, the provided salt melts to form a liquid reaction medium, and induces an at least partial oxidation of the organic components. At least one compound resulting from this oxidation is recovered. At least one alkali metal hydroxide includes water of crystallisation, acting as oxidising agent for the organic compounds in the reaction medium, in such a way as to participate in the production of dihydrogen, the latter being recovered for the reuse thereof.
Carbonized char fuels from biomass
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.
FLAVOR BRIQUETS
A flavor or aroma charcoal material, such as charcoal briquets, which is formulated to include a flavor or aroma component. The charcoal material may include a smoldering agent (e.g., limestone), wood particles (e.g., sawdust), a binder, and the flavor or aroma component (herbs and/or spices). The flavor or aroma charcoal material may not be configured as a fuel charcoal material, for example, it may be substantially void of char and/or coal. In an embodiment, the flavor or aroma charcoal material may be provided as part of a blend of different charcoal materials that includes both flavor or aroma briquets in combination with fuel briquets (e.g., which fuel briquets include char and/or coal, while the flavor briquets do not). The flavor briquets provide enhanced aroma and/or flavor to the grilling experience.
