  • Publication number: 20100144539
    Abstract: The present invention discloses an apparatus and method for rapid analysis of members of a combinatorial library. The apparatus includes a plurality of reactor vessels for containing individual library members, a fluid handling system that apportions a test fluid about equally between each of the vessels and a housing for enclosing the reactor vessels, the housing defining a pressure chamber, wherein the housing is configured to sustain a pressure substantially above atmospheric pressure. This allows for simultaneous screening of library members at high pressure by providing a small pressure differential on reactor components. The disclosed apparatus is especially useful for screening library members based on their ability to catalyze the conversion of fluid reactants.

  • Publication number: 20100127022
    Abstract: A valve is disclosed for dispensing small quantities of solid material in powder or granular form. The valve includes a valve housing defining a generally vertical flow passage through the housing, and a valve member rotatable in the valve housing about a generally horizontal axis of rotation between open and closed positions. In one embodiment, a slot is provided in the valve body. The valve body and slot are configured such that the slot communicates with both the inlet and the outlet of the flow passage when the valve member is open, and such that the slot communicates with the inlet but not the outlet of the flow passage when the valve member is closed. Other embodiments are disclosed.

  • Publication number: 20100113260
    Abstract: The present invention is directed to methods for making metal oxide compositions, specifically, metal oxide compositions having high surface area, high metal/metal oxide content, and/or thermal stability with inexpensive and easy to handle materials. In one embodiment, the present invention is directed to methods of making metal and/or metal oxide compositions, such as supported or unsupported catalysts. The method includes combining a metal precursor with an organic acid to form a mixture and calcining the mixture for a period of time sufficient to form a metal oxide material.

  • Publication number: 20100080733
    Abstract: A needle assembly has at least one guide member supported by a first body for sliding movement between an extended position and a retracted position. A second body is attached to the guide member. A biasing member biases the guide member to the extended position. A liquid handling needle is coupled to the first body so sliding movement of the guide member toward the retracted position retracts the second body relative to the liquid handling needle. The second body is adapted to contact a sealed receptacle. The biasing member urges the guide member toward said extended position during insertion and during said removal of the needle from the receptacle whereby the second body remains in contact with the sealed receptacle as the guide member moves from its extended position to its retracted position during said insertion and from its retracted position to its extended position during said removal.

  • Publication number: 20100081577
    Abstract: A reactor system includes a housing and a plurality of reactors at least partially contained in the housing. The reactors each have a containment structure enclosing an internal space in the reactor. The containment structure including a circumferential sidewall having opposite ends and surrounding at least a portion of said internal space. The sidewall has a thermal mass and a sidewall heater adjacent an exterior surface of the sidewall. The ratio of the thermal mass of the sidewall to a volume of the portion of the internal space that is surrounded by the sidewall is relatively low.

  • Patent number: 7687051
    Abstract: A method and catalysts for producing a hydrogen-rich syngas are disclosed. According to the method a CO-containing gas contacts a water gas shift (WGS) catalyst, in the presence of water, preferably at a temperature of less than about 450° C. to produce a hydrogen-rich syngas. Also disclosed is a water gas shift catalyst formulated from: a) Pt, its oxides or mixtures thereof, b) at least one of Fe and Rh, their oxides and mixtures thereof, and c) at least one member selected from the group consisting of Sc, Y, Ti, Zr, V, Nb, Ta, Mo, Re, Co, Ni, Pd, Ge, Sn, Sb, La, Ce, Pr, Nd, Sm, and Eu, their oxides and mixtures thereof. The WGS catalyst may be supported on a carrier, such as any one member or a combination of alumina, zirconia, titania, ceria, magnesia, lanthania, niobia, yttria and iron oxide. Fuel processors containing such water gas shift catalysts are also disclosed.
