  • Patent number: 8157899
    Abstract: A particulate material processing apparatus has a vessel and a processing tank. The vessel has a charging port for charging a particulate material into the vessel. The processing tank receives the particulate material charged from the charging port. The processing tank is shaped so as to narrow towards the bottom. At least the lower part of the processing tank is made of a gas-permeable material that allows the process gas for processing the particulate material to pass through. The upper part of the processing tank has lower gas permeability than the lower part of the processing tank.

  • Patent number: 8158071
    Abstract: A unit for use within a furnace which is absent a controlled atmosphere, for carrying out a synthesizing process for synthesizing precursors to form a synthesized product at elevated temperatures. The unit consists of a vessel, having at least one opening, for containing materials of the synthesizing process, and a solid reductive material. The materials of the synthesizing process are separated from the atmosphere of the furnace by either the vessel or the reductive material. The unit is especially suited for synthesizing LiFePO4 from Fe2O3, Li2CO3, carbon black, and phosphoric acid precursors.

  • Patent number: 8133438
    Abstract: A microfluidic device that comprises a microchannel structure in which there are one, two or more flow paths (101;201a,b;301a,a?,b) all of which comprises a porous bed I (104,204,304) that is common for all of the flow paths and exposes an immobilized reactant R that is capable of interacting with a solute S that passes through the bed. The characteristics are that at least one of the flow paths comprises/comprise a second porous bed II (105,205,305) that is placed upstream of porous bed I (104,204,304) and is dummy with respect to interaction with solute S but capable of interacting with a substance DS that is present in a liquid aliquot together with solute S and is capable of disturbing the result of the interaction between solute S and said immobilized reactant R. There is also disclosed a method utilizing the device and variant of the device in which the immobilized R is replaced with a generic affinity ligand LI and/or porous bed II exposes a generic ligand LII that may be different from LI.

  • Patent number: 8128886
    Abstract: A reactor which comprises a vessel (1) with a vessel bottom (2), a stirrer (3) arranged in the vessel, an emergency discharge valve (4) arranged in the vessel bottom for emptying the reactor in less than 600 seconds and at least one filtration device (5) arranged in the vessel bottom is suitable for the safe preparation of organic peroxides. The process for preparing an organic peroxide comprises the steps of preparing a solid hydroperoxide in the form of a suspension in the reactor, filtering the suspension through the filtration device (5) arranged in the vessel bottom (2) while retaining the solid hydroperoxide in the reactor and reacting the hydroperoxide with an alkylating agent, an acylating agent or a carbonyl compound.

  • Publication number: 20120000120
    Abstract: The present Invention relates to a hydrothermal process for the preparation of coal-like material from biomass, in which a reaction mixture comprising biomass is heated by contacting with steam, the steam moving counter-currently relative to the reaction mixture, to obtain a reaction mixture comprising activated biomass, and the activated biomass is subsequently polymerized to give a reaction mixture comprising coal-like material. According to another aspect, the present invention relates to a column, preferably a vertically oriented evaporation column, comprising horizontally oriented mass transfer trays, rotor elements mounted on a rotor shaft that is vertically oriented and passes through a rotor shaft opening in the mass transfer trays, and a housing provided with suitable upper and lower inlets and outlets. The column can be used with benefit in the hydrothermal process of the invention.
