  • Patent number: 8871676
    Abstract: Porous composites of mullite and cordierite are formed by firing an acicular mullite body in the presence of a magnesium source and a silicon source. In some variations of the process, the magnesium and silicon sources are present when the acicular mullite body is formed. In other variations, the magnesium source and the silicon source are applied to a previously-formed acicular mullite body. Surprisingly, the composites have coefficients of linear thermal expansion that are intermediate to those of mullite and cordierite alone, and have higher fracture strengths than cordierite at a similar porosity. Some of the cordierite forms at grain boundaries and/or points of intersection between mullite needles, rather than merely coating the needles. The presence of magnesium and silicon sources during acicular mullite formation does not significantly affect the ability to produce a highly porous network of mullite needles.

    Abstract: A mixed powder of AlH3 and MgH2 is ball-milled in a hydrogen atmosphere while applying force of 5 G through 30 G (in which G is gravitational acceleration), and the thus-obtained milled product is dehydrogenated to produce a hydrogen storage material. The hydrogen storage material comprises an amorphous phase containing an Al—Mg alloy as a mother phase, and a crystalline Al phase having a maximum length of 100 nm or less, the crystalline Al phase being distributed as a dispersed phase in the mother phase.

  • Patent number: 8318627
    Abstract: This invention relates to catalyst carriers to be used as supports for metal and metal oxide catalyst components of use in a variety of chemical reactions. More specifically, the invention provides a process of formulating a low surface area alpha alumina carrier that is suitable as a support for silver and the use of such catalyst in chemical reactions, especially the epoxidation of ethylene to ethylene oxide. A precursor for a catalyst support comprises an admixture of an alpha alumina and/or a transition alumina; a binder; and either a solid blowing agent which expands, or propels a gas upon the application of sufficient heat, and optionally contains talc and/or water soluble titanium compound.

  • Publication number: 20120264601
    Abstract: The invention relates to a method for producing an aluminium strip, in which the aluminium strip is coated with a sorption layer which has a binder and a sorbent. The object to propose a method for producing an aluminium strip coated with a sorption layer, by means of which an aluminium strip can be coated cost-effectively having constant performance characteristics with respect to the sorption of, for example, water vapour, is achieved according to the invention by means of a method for producing an aluminium strip coated with a sorption layer by applying a suspension to the aluminium strip in the coil-coating process, which in addition to a liquid comprises at least one binder, formed as a solid, and a sorbent, and by subjecting the aluminium strip, together with the applied suspension, to a drying process, in which the binder is activated.

  • Patent number: 8277638
    Abstract: A process is disclosed for converting heavy hydrocarbon feed into lighter hydrocarbon products. The heavy hydrocarbon feed is slurried with a catalyst comprising iron oxide and alumina to form a heavy hydrocarbon slurry and hydrocracked to produce lighter hydrocarbons. The iron oxide in the catalyst converts to catalytically active iron sulfide in the presence of hydrogen and sulfur.

  • Publication number: 20120222555
    Abstract: A gas separation process uses a structured particulate bed of adsorbent coated shapes/particles laid down in the bed in an ordered manner to simulate a monolith by providing longitudinally extensive gas passages by which the gas mixture to be separated can access the adsorbent material along the length of the particles. The particles can be laid down either directly in the bed or in locally structured packages/bundles which themselves are similarly oriented such that the bed particles behave similarly to a monolith but without at least some disadvantages. The adsorbent particles can be formed with a solid, non-porous core with the adsorbent formed as a thin, adherent coating on the exposed exterior surface. Particles may be formed as cylinders/hollow shapes to provide ready access to the adsorbent. The separation may be operated as a kinetic or equilibrium controlled process.

  • Patent number: RE44124
    Abstract: A regenerable, high-capacity sorbent for removal of mercury from flue gas and processes and systems for making and using the sorbent. A phyllosilicate substrate, for example vermiculite or montmorillinite, acts as an inexpensive support to a thin layer for a polyvalent metal sulfide, ensuring that more of the metal sulfide is engaged in the sorption process. The sorbent is prepared by ion exchange between the silicate substrate material and a solution containing one or more of a group of polyvalent metals including tin (both Sn(II) and Sn(IV)), iron (both Fe(II) and Fe(III)), titanium, manganese, zirconium and molybdenum, dissolved as salts, to produce an exchanged substrate. Controlled reaction of a sulfide ion source with the one or more polyvalent metals that are exchanged on the silicate substrate produces the sorbent. The sorbent is used to absorb elemental mercury or oxidized mercury species such as mercuric chloride from flue gas containing acid gases (e.g.
