  • Patent number: 8137431
    Abstract: The invention relates to a fertilizer granule comprising both a nitrate and urea as the main nitrogen source. A mineral added during production is an important component in the composition, said mineral stabilizing these otherwise poorly compatible nitrogen compounds. A high nitrogen content is thus attained with ammonium nitrate concentrations falling below maximum limit values set by international legislation and classification, while at the same time the explosion risk particularly associated with the use of ammonium nitrate is avoided. The invention is also directed to a process for the production of the fertilizer granule of the above type, said process resulting in a fertilizer granule with excellent resistance properties and a high nitrogen content, wherein said granule may be coated by methods typical in the art, if desired.

  • Patent number: 7367158
    Abstract: A fixing agent in the form of an oil/water type, lamellar emulsion or suspension in which the aqueous phase is the principal component, the aqueous phase containing water and a byproduct of agriculture or fermentation and the oil phase containing oil and emulsifiers. The emulsion or suspension is prepared by adding an aqueous solution to the oil phase in order to produce a water/oil type emulsion or suspension, by adding a portion of the aqueous phase in order to produce an inverse oil/water type emulsion or suspension, and by thereafter mixing the oil/water type emulsion or suspension with the remainder of the aqueous phase.

  • Patent number: 7147830
    Abstract: The invention relates to a method for producing thermally and mechanically stable ammonium nitrate by dissolving in nitric acid 1–3% by weight of reticulated metal silicate, before treatment with ammonia. The ammonium nitrate granules produced by this method swell very little, they do not considerably cake, and their granule strength is high.
