  • 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: 8308912
    Abstract: A method for pyrogasification of organic wastes that employs a vertical furnace filled with metal masses in the shape of metal toroids (2) previously raised to a high temperature (500 to 1100° C.) and organic materials to be pyrolyzed. It also employs a furnace for heating toroids transported by an Archimedes screw driven by a gear motor, as well as a separator for recovering the mineral residues, whereby separation between the toroids and residues is effected with the aid of a screen and an Archimedes screw driven by a gear motor.

  • Publication number: 20120241305
    Abstract: A pyrolyzer apparatus (i.e. a “cracking pipe”) comprises a first screen, a second screen, and a catalyst material positioned between the first and second screens. The pyrolyzer is structured so that feedstock is pyrolyzed and pyrolyzer-generated gas is drawn through the first screen, through the catalyst material, and then through the second screen in series. The gas may then be directed to other processing equipment so that bio-oil is extracted from the gas.

  • Patent number: 8266812
    Abstract: An apparatus for torrefaction of water containing cellulosic materials is performed in an inert atmosphere. The cellulosic material is cascaded through the apparatus between a plurality of rotatable trays vertically stacked within multiple processing zones. Steam being generated from heating of the cellulosic material is recycled back to the apparatus to provide an inert atmosphere. The steam may be superheated in a heat exchanger. Exhaust from the torrefaction zone of the apparatus has some moisture and other volatiles removed prior to being reheated in a burner. The heated exhaust is used in the heat exchanger to superheat the recycled steam.
