  • Patent number: 8759600
    Abstract: Apparatuses and methods are disclosed for contacting radially flowing fluids with solid particles (e.g., catalyst) with reduced tendency for fluidization of the particles, and especially a sealing portion of the particles at the top of a particle retention zone disposed between screens at upstream and downstream positions relative to radial fluid flow. Fluidization is reduced or eliminated by offsetting openings of the screens in the axial direction, such that upstream openings in the upstream screen are above highest downstream openings in a downstream stream. The offset in openings imparts a downward flow component to radially flowing fluid, thereby reducing solid particle fluidization without the need to induce a specific pressure drop profile along the entire axial direction of the screens.

The first reactant and the second reactant are mixed, thereby triggering a reaction between them to produce the biodiesel and glycerol, the mixing being convection-enhanced by shear stress induced circulation occurring within each slug of the reactants. The reaction takes place under a pressure that is less than 5 psi and under a temperature that is less than 70 degrees Celsius. Separation of the glycerol from the biodiesel occurs simultaneously with the mixing. Several microreactors are coupled in parallel to improve throughput of the biodiesel.

  • Patent number: 7901640
    Abstract: A new reactor design is presented for a counter-current flowing reactor. The reactor has a catalyst flowing down through the reactor, and over baffles. Gas is admitted under the baffles and flows up through the solid catalyst bed. The design includes slotted plates that extend from the bottom of the baffle in the reactor to a position near the catalyst outlet. The gas flows through the slotted plates and is directed up through the catalyst bed, while directing the flowing catalyst to the catalyst outlet ports.

  • Patent number: 7897120
    Abstract: A charging device for a tube reactor has a plurality of metering chambers which can be filled with filling material, for example a catalytically coated carrier material. Each metering chamber is adjoined by a drop tube or some other filling device via which a tube of the filling device can be filled in each case. The metering chambers can each be filled via antechambers which are combined into one replaceable antechamber unit.

  • Patent number: 7883675
    Abstract: The present invention provides a fuel treatment device which can realize easy separation and collection of a catalyst contained in the device. In a fuel treatment device (21) of the present invention a fuel gas is supplied to a catalyst, which fills a catalyst filling space (24) surrounded by a cylindrical inner circumferential wall and a cylindrical outer circumferential wall, to produce a reformed gas. The fuel treatment device (21) has a removal section indicator indicating a catalyst removal section (29) on the outer circumferential surface of the outer circumferential wall of the cylindrical catalyst filling space (24) and an opening formation assister assisting the formation of a catalyst removal opening for removing the catalyst.

  • Patent number: 7846399
    Abstract: A preferred embodiment of a system for loading catalyst and/or additives into a fluidized catalytic cracking unit includes a bin for storing at least one of the catalyst and/or additives, and a loading unit in fluid communication with the storage bin and the fluidized catalytic cracking unit on a selective basis. The loading unit is capable of being evacuated so that a resulting vacuum within the loading unit draws the catalyst and/or additive from the bin. The loading unit is also capable of being pressurized so that the catalyst and/or additive is transferred from the loading unit to the fluidized catalytic cracking unit.

  • Patent number: 7842259
    Abstract: An apparatus for contacting a bed of particulate material with a cross flowing fluid, which maintains the bed of particulate material within a retention volume. The apparatus includes partitions for retaining particles, with apertures disposed within the partitions. The apertures are covered by shrouds that extend above the edges of the apertures to prevent solid particles from spilling through inlet apertures.

  • Patent number: 7824631
    Abstract: A nanocarbon generation equipment designed such that organic processed materials can be quickly thermally decomposed therein and the decomposed materials are then quenched and liquefied to obtain liquefied materials is disclosed. This equipment comprises thermal reactor for quickly thermally decomposing the organic processed materials, apparatus for recovering the liquefied materials which are liquefied through quenching of thermally decomposed organic processed materials, a rotary furnace to be filled with a reducing atmosphere and loaded with hydrocarbons to be obtained through vaporization of liquefied materials after impurities contained in the liquefied materials are removed, and metal balls made of a metal selected from stainless steel, iron, nickel, chromium and an optional combination thereof, wherein the hydrocarbon introduced into the rotary furnace is decomposed into carbon and hydrogen, thus enabling nanocarbon to be produced through vapor-phase growth.

  • Publication number: 20100266844
    Abstract: The invention relates to a method of manufacturing a product having a sub-micron primary particle such as metal oxide, metal oxidhydroxide or metal hydroxide product, said method comprising the steps of: introducing a solid reactor filling material in a reactor, introducing a metal-containing precursor in said reactor, introducing a co-solvent into the said reactor, introducing a supercritical solvent in the said reactor. By these steps a contact between the metal-containing precursor and the co-solvent is established, thus resulting in the formation of said product in the proximity of the said solid reactor filling material. The present invention offers the astonishing possibility of producing anatase phase of TiO2 at temperatures as low as between 50° C. and 100° C. and at concurrent pressures of 100-200 bar. The invention also relates to a product such as anatase TiO2 produced by the method and also relates to an apparatus utilising the method.
