  • Patent number: 9434885
    Abstract: Methods for producing bio-oil from a feedstock (e.g., lignocellulosic) involving (1) pyrolyzing the feedstock in an inert atmosphere in a reactor to produce bio-oil, bio-char and non-condensable gases; (2) recycling 50 to about 85% of the non-condensable gases to the reactor to produce deoxygenated bio-oil; wherein the method is conducted in the absence of oxygen and wherein the method does not utilize externally added catalysts.
    Type: Grant
    Filed: February 26, 2013
    Date of Patent: September 6, 2016
    Assignee: The United States of America, as Represented by the Secretary of Agriculture
    Inventors: Charles A. Mullen, Akwasi A. Boateng, Neil M. Goldberg
  • Patent number: 9023181
    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: 8317883
    Abstract: Bio-oil from a feedstock selected from mustard family seeds, mustard family seed presscake, mustard family seed defatted presscake, and mixtures thereof. The bio-oil is produced by a method involving (1) pyrolyzing the feedstock to produce bio-oil, bio-char and non-condensable gases, (2) removing the bio-char from the bio-oil, (3) condensing the bio-oil, and (4) precipitating the bio-oil.

  • Publication number: 20100323435
    Abstract: The bio-fuel reactor injection system includes supplementing a biomass feedstock with a feedstock gas so that thermal conditions within the reactor body are optimized. The feedstock gas facilitates the flow of the feedstock through the feedstock injection system and maintains the feedstock below the feedstock's melting point until the feedstock is injected into the reactor body. In the preferred embodiment, the supplemental feedstock gas is nitrogen. The injection system also includes a plurality of screens that form a gas distributor plate. The gas distributor plate at least partially supports a fluidized bed within the reactor body. In the preferred embodiment, the nitrogen-supplemented feedstock is injected into the fluidized bed within the reactor.

  • Patent number: 6245294
    Abstract: The killing of microorganisms on the surface of porous and non-porous materials including agricultural commodities is accomplished by use of methods and apparatus which expose the material to controlled applications of a biocidal treatment gas into a sub-atmospheric environment. The material is first exposed to a vacuum then, without an intervening flush step, full treated with an air-free treatment gas prior to being re-exposed to a vacuum. The method and apparatus successfully kill microorganisms both on the surface and within the pores or structural recesses of the material without causing significant deleterious changes to the material.

  • Patent number: 6023855
    Abstract: The invention provides an air-assisted wiping device for use in a continuous-spray dryer. The air-assisted wiping device rotates inside the housing to continuously wipe heavy sticky powder from the walls of the housing using a wiper blade. The air-assisted wiping device includes an elongated hollow plenum having a flow-directing slot disposed along its length. Air received into the elongated hollow plenum is passed through the flow-directing slot onto a wiper blade, which is coupled to the elongated hollow plenum. The air discharged onto the wiper blade removes powder that collects on the leading side of the wiper blade.
