    摘要： A process for preparing a stabilized high cristobalite from a gel comprising ultramicroscopic particles of SiO.sub.2, Na.sub.2 O, and Al.sub.2 O.sub.3 where the ratio of moles of Na.sub.2 O to Al.sub.2 O.sub.3 is from about 0.95 to about 1.1, and the molar ratio of SiO.sub.2 to Al.sub.2 O.sub.3 is between about 10 and about 40. After the gel is formed, it is heated at 800-1400.degree. C. for a time sufficient to form stabilized high cristobalite.

    摘要： The present invention relates generally to a method for processing carbon dioxide gas (“CO2”). The method includes introducing a solution which includes a cation and a hydroxide and/or oxide to the CO2 to form a cation-containing carbonate salt; reacting the cation-containing carbonate salt with an acidic solution including a rare earth element to form a substantially solid, ionic rare earth element-containing carbonate salt material, the rare earth, cation-containing carbonate being substantially stable in the acidic solution such as to resist substantial formation of compounds selected from the group consisting of oxide, hydroxide and mixtures thereof; separating the rare earth element-containing carbonate salt material from the acidic solution; and reducing the rare earth element-containing carbonate salt material to a carbon-containing compound selected from the group consisting of carbon monoxide gas, elemental carbon and mixtures thereof.

    摘要： A biocompatible coating is formed on an aluminum sheet surface by reacting a surface portion with an aqueous solution containing calcium hydroxide and a more soluble calcium salt to form a hydrocalumite first coating. The first coating is then reacted with a water-soluble phosphate to form a biocompatible coating comprising hydroxyapatite. The hydroxyapatite coating may be reacted with a water-soluble fluoride or fluorophosphate to form a fluorapatite coating.

    摘要： Maleic anhydride is produced by passing a C.sub.4 to C.sub.12 hydrocarbon stream together with molecular oxygen over a fixed bed containing a vanadium molybdate catalyst promoted with a novel cobalt tantalate having the formulaCoTa.sub.b O.sub.xwherein b is a number from about 1.0 to about 4.0 and x is a number from about 3.5 to about 11.0. The catalyst is prepared by calcining a slurry containing cobalt oxide and tantalum oxide, or their precursors, in at a temperature range from about 525.degree. to about 1200.degree. C. for about 1 to about 40 hours to obtain a cobalt tantalate, which is then slurried with a mixture of oxides of vanadium and molybdenum, or their precursors, dried, and then calcined at a temperature from about 300.degree. to about 650.degree. C. for about 0.5 to about 24 hours. A support can be used for the catalyst.

    摘要： A method for making catalyst particles having improved resistance to surface area loss through thermal degradation. The particles are preferably metal oxide particles and more preferably alumina hydrate particles having a surface area of at least about 150 m.sup.2 /g. The particles are mixed with an organic monomer, preferably furfuryl alcohol. The monomer is polymerized to form polymer coated metal oxide particles. Thereafter, the polymer coated particles are treated with a phosphorus-containing acid or salt.
