Summary: This study investigated the enhancement of activated carbon porosity using hydrolyzed lignin extracted from black liquor. It was found that increasing H3PO4 concentration and impregnation time led to an increase in the specific surface area of the activated carbon. The activated carbon prepared from hydrolyzed lignin showed a promising adsorption capacity for cadmium. This research demonstrates a simple and low-cost method for producing highly porous activated carbon from pulp and paper industry waste.

Summary: In recent years, inorganic membrane filtration technology has emerged as a promising approach for treating papermaking black liquor and recovering lignin. However, the high cost associated with the preparation of most inorganic membranes hinders their industrial applications. In this study, a no-sintering, low-cost metakaolin-based geopolymer membrane (MGM) was developed using steel mesh as the substrate. By doping with slag, the MGM showed improved mechanical properties, microstructure, and separation performance. Compared to ceramic membranes prepared by sintering, the MGM offers cheaper raw materials and lower energy consumption, making it more suitable for industrial-scale applications.

Summary: Expenditure isolation of lignin and the understanding of its structural variations during different isolation processes are crucial for the high-value utilization of lignin. This study proposed a green deep eutectic solvent (DES) consisting of choline chloride, ethylene glycol, and 4-chlorobenzene sulfonic acid for rapid lignin separation from poplar. The structural variations of DES lignin and its relationship with alkali pre-extraction of hemicellulose were investigated. The results showed that alkali pretreatment enhanced the DES separation of lignin and promoted the cleavage of specific linkages, resulting in reduced molecular weight and thermal stability of isolated DES lignin. Moreover, DES lignin obtained from integrated utilization displayed higher purity and S/G ratio compared to lignin obtained from direct DES treatment.
