  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 oxidative cracking (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.

  本发明涉及一种生产一种或多种低分子量芳香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，将木质纤维素材料经过制浆过程，分离纸浆以提供含有改性木质素衍生组分的基本无纸浆过程流，分离改性木质素衍生组分，将分离的改性木质素衍生组分经过分解步骤，包括在催化剂或电氧化的影响下进行氧化裂解（裂解和氧化）或还原，然后将产生的产物经过隔离步骤，以提供一种低分子量芳香木质素衍生化合物。该化合物可以进一步通过环化等方式进行改性。该创新方法优选包括将该化合物进一步氧化为一种氧化还原活性化合物。此外，本发明涉及通过该创新方法获得的化合物以及用于执行该创新方法的装配。此外，本发明涉及一种用所述装配为现有的制浆和/或造纸制造工厂提供的方法。
