    • The present invention relates to a method for producing one or more low molecular weight aromatic lignin-derived compounds. The method preferably comprises providing lignocellulosic material, subjecting the lignocellulosic material to a pulping process, separating pulp to provide a substantially pulp-free process stream comprising a modified lignin-derived component, isolating the modified lignin-derived component, subjecting the isolated modified lignin-derived component to a decomposition step comprising cracking and oxidizing or reducing under the influence of a catalyst or electro-oxidation, and subjecting the resulting products to an isolation step, to provide a low molecular weight aromatic lignin-derived compound. Said compound may be further modified, e.g. by annulation. The inventive method preferably comprises further oxidizing said compound to a redox active compound. Additionally, the present invention relates to compounds obtainable by the inventive method and to an assembly for carrying out the inventive method. Furthermore, the present invention refers to a method for providing an existing pulp and/or paper manufacturing plant with said assembly.
    • 本发明涉及生产一种或多种低分子量芳族木质素衍生化合物的方法。 该方法优选包括提供木质纤维素材料,使木质纤维素材料经受制浆过程,分离纸浆以提供包含改性的木质素衍生组分的基本上无纸浆的工艺流,分离改性的木质素衍生的组分,使分离的改性的木质素 - 包括在催化剂或电氧化的影响下裂解和氧化或还原,并将所得产物进行分离步骤以提供低分子量芳族木质素衍生化合物的分解步骤。 所述化合物可以进一步修饰,例如, 通过annulation。 本发明的方法优选包括将所述化合物进一步氧化成氧化还原活性化合物。 此外,本发明涉及通过本发明方法可获得的化合物和实施本发明方法的组件。 此外,本发明涉及一种为现有纸浆和/或造纸厂提供所述组件的方法。
