  • the extruder premixes, extrudes, and cuts to length a composite biomass carbonaceous compact at about 500 to about 30,000 pounds per hour.
  • the innovative adhesive is added at a throat portion of the extruder, cuber, or mill.
  • the adhesive is added in a hopper portion of the extruder, cuber, or mill.
  • the adhesive is added in a die portion of the extruder, cuber, or mill and is configured to coat an exterior surface area of the composition of biomass materials.
  • the adhesive may be further divided within the processing step, wherein the starch is mixed with the biomass composition prior to forming, and the hydroxide is added during the forming.
  • the adhesive is added between wads of the plunger.
  • the adhesive is added at a plunger input and is configured to coat an exterior surface area of the composition of biomass materials at an exit die.
  • Brik Series by Dipiu Macchine Impianti; BHS Energy LLC; Wyoming, PA.; Warren & Barrg, Duapi, CA; or California Pellet Mill, Indianapolis, IN. may also be employed in accordance with the teachings of the present disclosure.
  • the shapeform of the composite biomass may be any number of geometric configurations, including but not limited to pellets, briquettes, pucks, and the corn kernel configuration.
  • the composite biomass is produced as a shapeform, it is partitioned into individual pieces.
  • the individual pieces may be the same size, or of varying sizes/lengths. In one form, the individual pieces are compatible with existing material handling.
  • the processing is performed at lower temperatures such that an endothermic reaction of the biomass materials and adhesive results. These temperatures are in the range of about 480°C to about 500°C for a roasting process, and similarly, 518°C - 572°C depending on the type of carbon material desired. Alternatively, the method may be performed at exothermic conditions followed by activation.

Abstract

L'invention concerne une matière compacte carbonée comprenant un corps contenant une composition de biomasse partiellement ou entièrement carbonée et un additif adhésif. L'additif adhésif comprend un amidon et un hydroxyde. La nature poreuse de la matière carbonée sert à retenir les nutriments ou de moyen de filtration. Le carbone est activé par réaction chimique ou thermique à partir de bois/coque pyrolysé(e). L'invention concerne un procédé permettant de traiter la matière compacte carbonée, ledit procédé consistant à associer une composition de matière de biomasse combustible, à sécher la composition, à ajouter l'additif adhésif, à ajouter d'autres additifs, par exemple de la silice et des bactéries utiles. La biomasse composite est traitée et façonnée, la forme obtenue étant divisée en morceaux individuels compatibles avec des procédés de manipulation existants. Dans un exemple, le traitement est effectué à environ 500 °C de manière à former un biocharbon; avec un traitement à plus de 518 °C - 572 °C, le carbone est formé par une activation ultérieure.
