The present invention relates to a process for the production of a liquid lignin composition, in particular to a method for obtaining a lignin composition using a compressed gas and acid assisted process, wherein a lignocellulosic biomass feedstock is treated with a polar organic solvent using an inorganic acid to assist in the release of lignin into the polar organic solvent and the use of compressed gas to keep the polar organic solvent in its liquid phase.
本发明涉及一种生产液态木质素组合物的工艺,特别是涉及一种使用压缩气体和酸辅助工艺获得木质素组合物的方法,其中木质纤维素生物质原料用极性有机溶剂处理,使用无机酸帮助木质素释放到极性有机溶剂中,并使用压缩气体使极性有机溶剂保持液相。
