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.
Abstract: A desulphurization reagent comprising an intimate mixture, in the solid state, of a main component selected from the group consisting of alkaline-earth, oxides, hydroxides, carbonates, bicarbonates, and mixtures, thereof, and an additive selected from the group consisting of 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.
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.
