  • Reagent for treating flue gases and method of preparation
    Patent number: 4233175
    Abstract: A reagent for treating flue gases constituted by an intimate mixture, in the solid state, of a main component selected from the group comprising alkaline-earth, oxides, hydroxides, carbonates, bicarbonates, and mixtures thereof, and an additive selected from the group comprising hydrogen halide acids, salts of such acids of alkaline metals, ammonium, and alkaline-earth metals, sulphuric acid, and mixtures thereof, said additive being present in an amount of from 0.1 to 15% by mole respect to said main component.

  • Gels containing iron and molybdenum
    Patent number: 4141861
    Abstract: An amorphous solid gel containing molybdenum and iron contains (a) ions of a ferric salt and ions from at least one salt containing, as simple cations, a metal M, in an atomic ratio M/ (Fe+M) from 0 to 0.5:1 (b) ions from a molybdic compound and ions from at least one salt containing, as oxygenated ions, a metal N, in an atomic ration N/ (Mo+N) from 0 to 0.5:1; and (c) water, wherein M is Co, Ni, Mn, Cr, Sc, Y or a rare earth metal, N is Cr, W, Mn, or V and (Mo+N) / (Fe+M) is 0.4:1 to 5:1.

    Date of Patent: September 19, 1978
    Assignee: Unibra
    Inventors: Bernard Delmon, Ghislain Van Houte
  • Method for the treatment of clay and products obtained
    Patent number: 4001362
    Abstract: The object of the invention is to provide a method for the treatment of all kinds of clay or any ceramic composition based on clay.The method consists in distributing in the clay metal ions capable of forming the corresponding oxide at a temperature at the most equal to the firing temperature of the clay thus treated, by maintaining the clay in contact with a liquid phase under conditions such that said ions pass at least in part into the liquid phase and a diffusion of said ions throughout the mass of clay is ensured.
    Type: Grant
    Filed: September 18, 1974
    Date of Patent: January 4, 1977
    Assignee: UNIBRA
    Inventors: Bernard Delmon, Jacques LeMaitre, Michel Bulens
  • Process for manufacturing gels containing iron and molybdenum and the uses thereof
    Patent number: 4000085
    Abstract: Gels containing molybdenum and iron and optionally other metals, are useful in the production of catalysts or as optical filters. They are produced by conducting essentially a solid - solid reaction between a compound of molybdenum, e.g. ammonium molybdate, and a ferric compound, e.g., ferric nirate, thereby obtaining the same ratio of molybdenum and ferric contents in the gels, as used in the starting materials. Furthermore, the resultant gels are highly homogeneous, and when used as catalysts, the yields of the process are up to plus 99%.
