Abstract:
Disclosed is a composite material, in particular a homogeneous composite material designed as a molded article and/or suitable for the production of molded articles. Said composite material is made of polymer materials and lignite and/or leonardite and/or xylite and mineral components obtained from igneous rock and/or phyllosilicate, expands under the effect of liquids, especially water, aqueous solutions, and aqueous oil emulsions, and is suitable to store said liquids, form hydrogel, and discharge said hydrogel.
Abstract:
According to the present invention, there is provided a process for the manufacture of sulphur- containing fertilizer compositions, said process comprising the steps of: a) providing a slurry of at least one phosphate-based fertilizer material selected from the group consisting of ammonium phosphates, ammonium phosphate based nitrogen-phosphorus-potassium (NPK) compounds, super phosphates and partially acidulated phosphate rocks; b} bringing said slurry into contact with at least one surfactant and elemental sulphur; and c) introducing the mixture obtained in step b) into a granulator unit in order to obtain granules of the fertilizer composition, wherein the elemental sulphur is present in an amount in the range of form 1 to 25 wt.%, based on the total weight of the fertilizer composition The present invention also provides a fertilizer composition.

Abstract:
1.1. The invention relates to a method for producing tables made of mixtures of a plurality of materials, and method for producing a sulfurous fertilizer. 2.1. The invention relates to a method for producing tablets made of mixtures of a plurality of materials, particularly urea mixtures, having the following steps: - producing a liquid melt of a first material, - adding at least one further material in solid or liquid form to the melt for producing a mixture, - output of drops of the mixture onto a steel belt by means of a drop former having a rotating, perforated outer drum, - solidification of the drops of the mixture on the steel belt into tablets, wherein the at least one additional material is mixed into the liquid melt in liquid form immediately before the drop former or into the liquid melt in solid form upstream of a two-stage heated grinding and mixing unit. 2.2. Use for producing fertilizer, for example.
Abstract:
The present invention relates to hydronium stabilized silicic acid nanoparticles able to dissolve in aqueous environments, to their preparation and use. The present invention provides a stable suspension of colloidal silicic acid nanoparticles having a pH lower than 0.9, a molar silicon concentration between 0.035 and 0.65, a free water concentration of at least 30% (w/v) and a ratio between hydronium ion and Si molar concentrations higher than 2 and preferably inferior to 4. The present invention further provides a method for preparing a stable suspension of colloidal silicic acid nanoparticles, which comprises the steps of providing an aqueous inorganic or organic silicon solution and quick mixing said aqueous inorganic or organic silicon solution with water containing a strong acidic compound at a temperature inferior at 30°C, preferably comprised between 1 and 25°C, to form a suspension of colloidal silicic acid nanoparticles having a pH lower than 0.9, stabilized by hydronium ions, the ratio between hydronium ions and Si molar concentrations being higher than 2 and preferably inferior to 4, for a molar silicon concentration between 0.035 and 0.65 and a free water concentration of at least 30% (w/v).
