Directly Heated Chamber Patents (Class 202/208)
  • Patent number: 8961743
    Abstract: An improved rapid thermal conversion process for efficiently converting wood, other biomass materials, and other carbonaceous feedstock (including hydrocarbons) into high yields of valuable liquid product, e.g., bio-oil, on a large scale production, is disclosed. In the process, biomass material, e.g., wood, is fed to a conversion system where the biomass material is mixed with an upward stream of hot heat carriers, e.g., sand, that thermally convert the biomass into a hot vapor stream. The hot vapor stream is rapidly quenched with quench media in one or more condensing chambers located downstream of the conversion system. The rapid quenching condenses the vapor stream into liquid product, which is collected from the condensing chambers as a valuable liquid product.

  • Patent number: 8585868
    Abstract: A device for pyrolysing biomass comprises: a reactor space; a first feed for biomass material connecting to the upper zone thereof; a second feed for heated heat carrier material connecting to the upper side of the reactor space; a first discharge for pyrolysis gas connecting to the upper zone of the reactor space at a distance from the first feed; and a second discharge for solid material, for instance carbon and heat carrier material, connecting to the underside of the reactor space. A substantial separation between the discharge flows of pyrolysis gas and solid material takes place predominantly under the influence of gravitational force, without interposing of a cyclone. The reactor space is modeled such that the direct flow from the first feed and the second feed to the first discharge is blocked. A mechanical mixer is present in the reactor space for the purpose of mixing the flow of biomass material with the flow of preheated heat carrier material.

    Abstract: The present invention relates to means of thermally decomposing organic material feedstocks to produce energy, combustible fuels, usable materials, and the ability to sequester carbon. The organic material feedstocks could come from municipal or industrial waste streams, produce from agriculture operations, or from mining operations such as coal or shale. The present invention provides superior temperature control and heat transfer characteristics and enables novel and unique means of heat exchange between endothermic and exothermic reactions in the process stream. This invention provides a sort of “fractional distillation” arrangement enabling the opportunistic capture of gaseous and liquid hydrocarbon fuel components, contaminants, and selected organic or inorganic species or components of the feedstock material.

  • Patent number: 7736471
    Abstract: A system for treating a feedstock for the purposes of waste destruction, energy generation, or the production of useful chemicals is disclosed and includes a reactor vessel. A heating lance is configured to outflow the products of a partial oxidation reaction into a reaction chamber in the vessel. The hot reaction products heat and pyrolyze the feedstock in the chamber generating a process effluent which typically includes gases (e.g. syn-gas) and carbon solids. Glasses and metals in the feedstock accumulate in the chamber in a molten state. The molten materials store thermal energy and provide thermal stability to the treatment system. A recycle loop uses carbon solids from the process effluent as an input to the lance for reaction with an oxidant therein.

  • Publication number: 20080210536
    Abstract: A process for treating solid organic materials, especially for recycling treated wood, uses energy provided by hot gases at the bottom of a reactor column to perform a distillation operation which ensures splitting of organic bonds in the material and uses, as the distillation operation progresses, constant control between a first temperature of the hot gases before they are introduced into the lower part of the reactor column and a second temperature of a layer of the material located in an area immediately above the grid of the reactor column. When the first temperature and the second temperature are identical or virtually identical, corresponding to removal of all the organic bonds of the material by evaporation and transport by the hot gases from the bottom to the top of the column, the layer of material at the second temperature is removed in order to collect a material that largely consists of carbon and constitutes a secondary raw material.

  • Patent number: 6013158
    Abstract: An apparatus for forming liquid hydrocarbons from solid coal. The coal is pulverized to provide a particulate coal feed, which is then extruded to provide a hollow tube of compressed coal supported inside of a support tube. A clay feed is extruded to provide a hollow tube of compressed clay supported inside of the coal tube and a combustible fuel is burned inside of the clay tube. The temperature of combustion is sufficient to fire the extruded clay and pyrolyze the extruded coal to produce hydrocarbon gases and coal char. The support tube has holes for releasing the hydrocarbon gases, which contain suspended particles formed during combustion. The suspended particles are removed from the hydrocarbon gases to provide clean gases, which are passed through an ionizing chamber to ionize at least a portion thereof. The ionized gases are then passed through a magnetic field to separate them from each other according to their molecular weight.

  • Patent number: 4523979
    Abstract: Retorted shale particles are recovered from a retort and delivered to a gas lift for transport to a fluidized combustor by passage, serially, through a sealing vessel, a crusher preferably operating at retort pressure, and a surge vessel. In the sealing vessel, a sealing gas is introduced, and after commingling with the shale, the gas passes countercurrently to the shale and enters the retort, thus sealing the retort gases in the retort while separating the retorted shale from the retort gases. Retorted shale from the sealing vessel is transported to a crusher, wherein the shale is reduced in size to that suitable for combustion under fluidized conditions. To prevent the crushed shale from packing, the shale is passed to a surge vessel, wherein the crushed shale is held as a fluidized bed, from which the crushed shale is continuously withdrawn at a regulated rate and introduced into the gas lift leading to the fluidized combustor.
