The product film has a very uniform stoichiometry throughout the reactor. Similarly, vapors of diisopropylphosphate react with vapors of lithium bis(ethyldimethylsilyl)amide to deposit lithium phosphate films on substrates heated to 250° C. Supplying the vapors in alternating pulses produces these same compositions with a very uniform distribution of thickness and excellent step coverage.

  • Patent number: 8961821
    Abstract: A process of treating a gas stream containing mercury and acid gas pollutants is disclosed. The process includes applying a sorbent composition into a gas stream in order to adsorb mercury containing compounds and acid gas pollutants. The sorbent composition includes a compound having the formula (SiO2)x(OH)yMzSaF.B. The combination of basic inorganic solids for the adsorption of acid gases, and metal sulfide-doped silica for the adsorption of mercury provides dual sorbent functionality, along with additional benefits for each individual sorbent: silica for moisture retention on the surface of the basic inorganic particle and adsorption of acid gas, which will improve metal sulfide performance at higher operating temperatures. The use of a hygroscopic solid effectively dries the metal sulfide-doped silica slurry without the use of filtration of drying equipment, providing significant economic benefit for the manufacture of metal sulfide-doped silica material.

  • Patent number: 8932545
    Abstract: A method is provided for the synthesis of a mesoporous lithium transition metal compound, the method comprising the steps of (i) reacting a lithium salt with one or more transition metal salts in the presence of a surfactant, the surfactant being present in an amount sufficient to form a liquid crystal phase in the reaction mixture (ii) heating the reaction mixture so as to form a sol-gel and (iii) removing the surfactant to leave a mesoporous product. The mesoporous product can be an oxide, a phosphate, a borate or a silicate and optionally, an additional phosphate, borate or silicate reagent can be added at step (i). The reaction mixture can comprise an optional chelating agent and preferably, the reaction conditions at steps (i) and (ii) are controlled so as to prevent destabilization of the liquid crystal phase. The invention is particularly suitable for producing mesoporous lithium cobalt oxide and lithium iron phosphate.

  • Patent number: 8877670
    Abstract: Catalysts are disclosed comprising fibrous substrates having silica-containing fibers with diameters generally from about 1 to about 50 microns, which act effectively as “micro cylinders.” Such catalysts can dramatically improve physical surface area, for example per unit length of a reactor or reaction zone. At least a portion of the silica, originally present in the silica-containing fibers of a fibrous material used to form the fibrous substrate, is converted to a zeolite (e.g., having a SiO2/Al2O3 ratio of at least about 150) that remains deposited on these fibers. The fibrous substrates possess important properties, for example in terms of acidity, which are useful in hydroprocessing (e.g., hydrotreating or hydrocracking) applications.

    Abstract: Granular crystalline silicotitanate (CST) is supplied from an adsorbent raw material supply apparatus into a caustic treatment apparatus. A sodium hydroxide solution of 1 Mol/L in a caustic agent supply apparatus is supplied into the caustic treatment apparatus with the granular CST supplied. After a predetermined quantity of the sodium hydroxide solution is supplied to the caustic treatment apparatus, the supply of the sodium hydroxide solution to the caustic treatment apparatus is stopped. The granular CST is left to stand for 0.5 hour in the state that it is immersed in the sodium hydroxide solution in the caustic treatment apparatus and is subjected to the caustic treatment. After that, the granular CST subjected to the caustic treatment is cleaned by cleaning water in a cleaning water supply apparatus. The respective adsorptive performances of cesium and strontium of the granular CST subjected to the caustic treatment are improved more.
