  • Patent number: 10889795
    Abstract: Discharging pretreated biomass from a pretreatment reactor and mixing the discharged pretreated biomass with a cooling liquid in a vessel provides a cooled slurry having a consistency that is less than about 12 wt %. Since the consistency is relatively low, the cooled slurry may be pumped to a higher elevation using standard pumping equipment. At the higher elevation, the cooled slurry may be separated into a first stream comprising a liquid component of the slurry and a second other stream comprising a solid component of the slurry (e.g., having a consistency between about 15 wt % and 40 about wt %). The solid component may be fed to an inlet of a hydrolysis reactor, while the liquid component may be fed to a cooling system that provides a cooled stream. The cooled stream may then be cycled back to the vessel.

  • Patent number: 9624516
    Abstract: A method produces a sugar liquid by repeating a sugar liquid production process including (1) to (3): (1) adding a filamentous fungus-derived cellulase to cellulose to perform primary hydrolysis; (2) adding a fresh filamentous fungus-derived cellulase to the hydrolysate in Step (1) to perform secondary hydrolysis; and (3) subjecting the hydrolysate in Step (2) to solid-liquid separation to obtain a sugar liquid, from which a recovered enzyme is obtained; wherein the recovered enzyme obtained in Step (3) is used for Step (1) of the next and later sugar liquid production processes.

  • Patent number: 9593355
    Abstract: The present invention concerns a production of liquefied lignocellulosic substrate by enzymatic reaction. 10% to 40% by weight dry matter of pre-treated lignocellulosic substrate is contacted, with water and enzymes at 0.1 to 60 mg of enzymes per gram of cellulose for a period of 1 to 24 hours. Over time, at least the value of one of the rheological characteristics of the reaction medium is measured. If a reduction of the value is detected over time, the following step a) is carried out: a) the feeding flow rate of pre-treated lignocellulosic substrate is increased, with or without modification of the flow rate of enzymes and/or water; If an increase of the value is detected over time, a step b) is carried out: b) the feeding flow rate of water and/or enzymes is increased, with or without modification of the flow rate of pre-treated lignocellulosic substrate.

  • Patent number: 9410960
    Abstract: A method of diagnosing galactosemia in blood samples from neonates by determining GAL-1-P concentrations before 5-7 days of life is disclosed. The removal of interfering compounds allows a more specific and therefore more accurate determination of GAL-IP levels in newborn screening for galactosemia using mass spectrometry. This is of major importance when investigating samples from children that have not yet achieved a steady state of GAL-IP (i.e. before 5-7 day of life).

  • Patent number: 9394548
    Abstract: Wheat bran culture mix is used to inoculate organic waste and produce an inoculated waste material, where the wheat bran culture mix includes soil derived microbes. The inoculated waste material is shredded to produce shredded inoculated waste material which is fermented the shredded inoculated waste material for at least 7 days. Contents from the fermenter are then transferred into a dewatering device to produce dewatered contents which are then separated into soluble and suspended products.

  • Patent number: 9234140
    Abstract: A rotary machine type shock wave reactor suitable for thermal cracking of hydrocarbon-containing materials includes a casing, a rotor whose periphery contains an axial-flow blade cascade, and a directing rim, provided with at least two stationary vane cascades, adjoining an axial-flow rotor cascade, wherein the casing substantially encloses the periphery of the rotor and the directing rim. The cascades are configured to direct feedstock containing process stream to repeatedly pass the cascades in a helical trajectory while propagating within the duct between the inlet and exit and to generate stationary shock-waves to heat the feedstock. The axial-flow rotor cascade is configured to provide kinetic energy and add velocity to feedstock containing process stream, and the stationary vanes located downstream the rotor cascade are configured to reduce the velocity of the stream and convert kinetic energy into heat. The reactor may also process carbohydrate-and glyceride-based feedstock, and gaseous biomass matter.

    Abstract: The invention relates to improvements in the production of ethanol and acetate by microbial fermentation, particularly to production of alcohols by microbial fermentation of a substrate comprising CO and the addition of an inorganic sulfur additive. It more particularly relates to the provision of an inorganic organic sulfur source to a fermentation system such that one or more microorganisms convert a substrate comprising CO to ethanol. In one aspect the invention uses a sulfur additive comprising inorganic sulfur compounds having a +2 to a +4 sulfur oxidation state that produces sulfur oxoanions and hydrosulfur oxoanions in an aqueous fermentation medium.
