20080207435 | Hydroconversion catalysts and methods of making and using same - Stable catalyst carrier impregnating solutions can be prepared using a component of a Group VIB metal, e.g., molybdenum, at high concentration, a component of a Group VIII metal, e.g., nickel, at low concentration, and a phosphorous component, e.g., phosphoric acid, at low concentration, provided that the Group VIII metal is in a substantially water-insoluble form and a particular sequence of addition of the components is followed, even when a substantially water-insoluble form of the Group VIB component is used. The resulting stabilized impregnating solution can be supplemented with additional Group VIII metal in water-soluble form to achieve increased levels of such metal in the final catalyst. Furthermore, uncalcined catalyst carriers impregnated with the stable solution and subsequently shaped, dried and calcined, have unexpectedly improved performance when used in the hydroprocessing of heavy hydrocarbon feedstocks. High conversion can be achieved at reduced levels of sediment, especially in comparison to standard commercial catalysts. | 08-28-2008 |

20110212829 | HIGH SURFACE AREA CERAMIC CATALYSTS AND THE MANUFACTURE THEREOF - A process for making a ceramic catalyst material includes mixing a catalyst precursor material with a mineral particulate to form a mixture; adding a binder, silicon carbide, and a parting agent to the mixture to form unfired spheroids; and heating the unfired spheroids at a temperature effective to oxidize the silicon carbide and the catalyst precursor material to form the ceramic catalyst material. In another embodiment, the process includes the addition of a catalyst metal oxide salt to an aluminosilicate hydrogel aggregate mixture. Once the mixture sets, the set mixture is heated to a temperature to effective to produce a high surface area ceramic catalyst material. | 09-01-2011 |
20110212830 | REMOVING OIL FROM SURFACE USING DRY AMORPHOUS SILICA PRODUCT WITH INERT CARRIER - A dry product that permanently removes oil and oil stains from liquid or dry surfaces and is environmentally safe. The dry product is formed by mixing efficacious proportions of untreated amorphous silica with a dry, inert organic, inorganic or synthetic carrier, or combinations of said carriers. Suitable inert carriers include, but are not limited to, (a) inert inorganic carriers including, but not limited to, clays, perlite, vermiculite, crushed glass, volcanic ash and sand; (b) inert organic carriers, including, but not limited to, peat moss, straw, hay, sawdust, ground corncobs, flours, and coconut coir, and (c) inert synthetic carriers, including, but not limited to, polyurethane, polyethylene and polypropylene. The dry product can be applied directly to oil stains either on a hard surface, such as concrete or asphalt, or to oil spills on water. | 09-01-2011 |
20140221193 | FLUIDIZED BED WATER GAS SHIFT CATALYST - The present invention relates to an aqueous gas-converting catalyst composition comprising: an active component; a support; an inorganic binder; at least one accelerator selected from the group consisting of cobalt oxide, molybdenum oxide, nickel oxide, calcium oxide, barium oxide, strontium oxide, magnesium oxide, zirconium oxide, manganese oxide and barium titania; and at least one stabilizer selected from the group consisting of magnesium oxide, zirconium oxide, stabilized zirconia, and hydrotalcite. The catalyst according to the present invention can effectively capture and separate carbon dioxide due to the excellent physical properties thereof such as packing density and abrasion resistance, and high CO conversion. Also, according to the present invention, mass production is facilitated by applying a spraying technique, and overall costs are lowered because of high yield. Thus, the present invention can be applied as a low cost pre-combustion CO2 capturing technique to an integrated gasification combined cycle, fuel cells, coal liquefaction, compound production, and the like. | 08-07-2014 |
