  • Patent number: 10689728
    Abstract: The present disclosure relates to hydrometallurgical technologies wherein liquid-liquid extraction, also called solvent extraction, is used to separate and concentrate metal ions. Exemplary embodiments relate to solvent extraction of copper and a diluent useful in copper solvent extraction. A bio-based composition can fulfil physico-chemical properties that are desired for solvent extraction. Moreover, a composition is disclosed, which in addition to providing more environmental friendly alternative, can also improve the solvent extraction process of copper.

  • Publication number: 20200010768
    Abstract: A method comprises conducting hydrodeoxygenation and optionally isomerization of raw material, wherein the method further comprises one or more solvent extraction steps and optionally hydrogenation to remove aromatic and/or naphthenic hydrocarbons from the material. The original aromatic and/or naphthenic content of the raw material is less than 21 vol-%. In the method, the aromatic and/or naphthenic content is reduced by more than 45%, preferably by more than 60%. A composition contains hydrocarbons produced by said method, wherein the total aromatic and/or naphthenic hydrocarbon content of the composition is less than a predefined low value, and C15-C20 i-paraffins are the main fraction of the hydrocarbon content of the composition, weight basis.

  • Patent number: 9657147
    Abstract: The present invention relates to a method for preparation a glycolide polyester by ring opening polymerization characterized in that glycolide monomer with optional co-monomer(s) of cyclic ester(s) is/are subjected to ring opening polymerization in the presence of a dispersion stabilizer and a catalyst, said catalyst being selected for precipitating glycolide homopolymer or copolymer from solvent, said solvent being selected so that the glycolide monomer and the optional co-monomer(s), the dispersion stabilizer and the catalyst are soluble therein but said glycolide homopolymer or copolymer is non-soluble. The present invention further relates to an in situ ring opening polymerizing process product, and to use of said glycolide polyester, and to further processing of said glycolide polyester.
