  • 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.

    Abstract: Inclusion of a needle structured clay or the plate structured clay sodium montmorillonite in a chitosan film was found to reduce shrinkage of the film. The needle structured clay is purified and processed into a substantially dispersed form by subjecting an aqueous slurry of the clay with water-soluble phosphate dispersant to a high pressure, high shear mixing process or to sonication. Laminates fabricated from chitosan film including dispersed clay can be used in make a variety of finished articles that can be used to provide protection from hazardous chemical and biological agents.

    Abstract: Increasing the activity of a hydrous magnesium silicate with respect to sequestration of carbon dioxide by mineral carbonation includes rapid heating of the hydrous magnesium silicate. Rapid heating of the hydrous magnesium silicate includes heating a quantity of particles of hydrous magnesium silicate with flame conditions to substantially dehydroxylate the particles. The dehydroxylated particles can be contacted with carbon dioxide in a sequestration process to form magnesium carbonate.

  • Patent number: 8202501
    Abstract: The invention relates to a method for preparing a synthetic talc composition. According to said method, a kerolite composition is subjected to an anhydrous thermal treatment carried out at a pressure lower than 5 bar, from over a few hours up to over a few days, at a treatment temperature higher than 300° C. The invention also relates to a synthetic talc composition prepared in this way, the synthetic talc particles of the composition being exclusively of chemical formula —(Si4)Mg3O10(OH)2— and identifiable, during X-ray diffraction, by the presence of a characteristic diffraction peak located at a distance of between 9.40-9.68 and corresponding to a plane (001). Said synthetic talc particles also have a thermally stable crystalline structure of stacked laminae, which is very similar to that of a natural talc and has a particle size smaller than approximately ten micrometers.

  • Publication number: 20120131973
    Abstract: A filter for treating CO2 from a CO2-emitting industrial plant, takes advantage of the fact that peridotite igneous rocks (or material of similar chemical content: basalt, gabbro, dunite, amphibolites, artificially produced Ca, Mg oxides) which are abundant on and close to the Earth's surface, can absorb and contain CO2 gases resultant from industrial activity. This chemical process occurs naturally, but has not been utilized to capture high concentrations of CO2 emitted into the atmosphere. Calcium and magnesium oxides of the peridotite react with CO2 to form stable carbonate minerals. The invention enhances and expedites this natural process for the remediation of industrial pollutants such as CO2 from the oil, gas, coal, cement/concrete and like CO2-emitting industries, and provides a resource for materials in construction (concrete), steel, aviation and agricultural and other industries.

    Abstract: The use of talc as a fire performance modifier in polymer compositions is disclosed, in which the talc is present in an amount less than 30 percent by weight of the total weight of the polymer composition, and also in amounts ranging from 5 to 30 percent by weight of the polymer composition. In such polymer compositions, the impact performance of the composition is not compromised, the composition, for example, being useful in manufacture of plastic and polymer based pallets for storage and for warehouse use. Talc is disclosed to act as a fire performance modifier and char agent at concentrations as low as 5 weight percent in polymer compositions by modifying the Heat Release Rate shown by, first, lowering the Peak Heat Release, and second, by shortening the time period to reach the Peak Heat Release compared to the virgin polymer resin.

  • Patent number: 8088349
    Abstract: Disclosed is a clean method for preparing layered double hydroxides (LDHs), in which hydroxides of different metals are used as starting materials for production of LDHs by atom-economical reactions. The atom efficiency of the reaction is 100% in each case because all the atoms of the reactants are converted into the target product since only M2+(OH)2, M3+(OH)3, and CO2 or HnAn? are used, without any NaOH or other materials. Since there is no by-product, filtration or washing process is unnecessary. The consequent reduction in water consumption is also beneficial to the environment.
