The invention relates to an improved process for separating lignin and monomeric sugars from a liquor comprising lignin and monomeric sugars in a solvent mixture of water and at least one organic solvent, which employs membrane filtration techniques such as nanofiltration and selective water removal, preferably by permeation through a membrane which is selective for water molecules. The invention further relates to a modular system for executing the process according to the invention. The process and system according to the invention are particularly suitable to be incorporated with pre-treatment of lignocellulosic biomass, in particular by organosolv fractionation or solvolysis.
本发明涉及一种改进的工艺,用于从在水和至少一种有机溶剂的混合溶剂中含有木质素和单体糖的液体中分离木质素和单体糖,该工艺采用膜过滤技术,如纳滤和选择性脱水,最好是通过对水分子有选择性的膜进行渗透。本发明还涉及一种用于执行本发明工艺的模块化系统。根据本发明的工艺和系统特别适合与木质纤维素生物质的预处理相结合,尤其是通过有机溶胶分馏或溶解。
