Title (EN) PREPARATION METHOD FOR MODIFIED LIGNIN AND FERTILIZER COMPOSITION CONTAINING MODIFIED LIGNIN
(FR) PROCÉDÉ DE PRÉPARATION DE LIGNINE MODIFIÉE ET COMPOSITION D'ENGRAIS CONTENANT DE LA LIGNINE MODIFIÉE
(KO) 변성 리그닌의 제조 방법 및 변성 리그닌을 포함하는 비료 조성물
Abstract:
(EN) The present invention relates to a preparation method for modified lignin, the method comprising the steps of: mixing hydrogen peroxide and lignin cakes to prepare a lignin solution; adding an iron ion to the lignin solution; centrifuging the iron ion-added lignin solution to remove a supernatant; and drying solids remaining after the removal of the supernatant, wherein the lignin cakes are prepared by acid hydrolysis of lignocellulosic biomass. The present invention also relates to a fertilizer composition containing the modified lignin.
(FR) La présente invention concerne un procédé de préparation de lignine modifiée, le procédé comprenant les étapes consistant à : mélanger du peroxyde d'hydrogène et des gâteaux de lignine pour préparer une solution de lignine ; ajouter un ion de fer à la solution de lignine ; centrifuger les ions de fer ajoutés à la solution de lignine pour éliminer un surnageant ; et sécher les solides restant après l'élimination du surnageant, les gâteaux de lignine étant préparés par hydrolyse acide de biomasse lignocellulosique. La présente invention concerne également une composition d'engrais contenant la lignine modifiée.
(KO) 본 발명은 과산화수소 및 리그닌 케이크를 혼합하여 리그닌 용액을 제조하는 단계; 상기 리그닌 용액에 철 이온을 첨가하는 단계; 상기 철 이온이 첨가된 리그닌 용액을 원심분리하고, 상층액을 제거하는 단계;및 상층액이 제거되고 남은 고형물을 건조하는 단계를 포함하며, 상기 리그닌 케이크는 목질계 바이오매스를 산 가수분해시켜 제조하는 것인, 변성 리그닌의 제조 방법에 대한 것이다. 또한 본 발명은 상기 변성 리그닌을 포함하는 비료 조성물에 대한 것이다.
