  • Patent number: 8969229
    Abstract: The present invention generally relates to high rate adsorbents and a method for their manufacture involving the steps of component mixing, extrusion, spheronization and calcination. The component mixing can involve both dry mixing in addition to wet mixing of an adsorbent with a binder, if required, and a fluid such as water. The paste so formed from the mixing stage is extruded to produce pellets which are optionally converted to beads by spheronization using in one embodiment, a marumerizer. The product is harvested and calcined to set any binder or binders used and/or burn out any additives or processing aids. This basic manufacturing scheme can be augmented by extra processing steps including ion exchange and activation to alter the composition of the adsorbents, as required.

    Abstract: A process for manufacturing low soluble iron, medium flow rate diatomite filter aids and such filter aids are disclosed. Sodium aluminate is used as an additive. As compared to either straight calcined or soda ash flux-calcined diatomite filter aids of similar permeabilities made from the same ore, the disclosed filter aids have much lower iron solubilities. For instance, disclosed filter aids of about 0.3 to about 2.0 Darcy were made using an alkali aluminate as an additive/flux agent to have an EBC soluble iron content of less than 100 ppm versus more than 140 ppm for similar filter aids that were made from the same ore and flux-calcined with soda ash.

  • Patent number: 7709410
    Abstract: The invention relates to Group 1 metal/silica gel compositions comprising silica gel and an alkali metal or an alkali metal alloy. The compositions of the inventions are described as Stage 0, I, II, and III materials. These materials differ in their preparation and chemical reactivity. Each successive stage may be prepared directly using the methods described below or from an earlier stage material. Stage 0 materials may, for example, be prepared using liquid alloys of Na and K which are rapidly absorbed by silica gel (porous SiO2) under isothermal conditions, preferably at or just above room temperature, to form loose black powders that retain much of the reducing ability of the parent metals. When the low melting Group 1 metals are absorbed into the silica gel, a mild exothermic reaction produces Stage I material, loose black powders that are indefinitely stable in dry air. Subsequent heating to 400° C. produces Stage II materials, which are also loose black powders. Further heating above 400° C.

  • Patent number: 7510996
    Abstract: A hydrogen storage material is expressed by a composition formula, (Ca1-xAx)1-z(Si1-yBy)z, wherein “A” is at least one member selected from the group consisting of alkali metal elements, alkaline-earth metal elements, rare-earth elements, the elements of groups 3 through 6, Ni, Au, In, Tl, Sn, Fe, Co, Cu and Ag; “B” is at least one member selected from the group consisting of the elements of groups 7 through 17, rare-earth elements, Hf and Be; 0?x<1 by atomic ratio; 0?y<1 by atomic ratio; and 0.38?z?0.58 by atomic ratio. It is lightweight as well as less expensive. In principle, neither high-temperature nor high-pressure activation is required, because it exhibits a high initial activity. The operation temperature can be lowered and the hydrogen absorption content can be enlarged by controlling the kind and substitution proportion of the substituent elements appropriately.
