The accumulation of metal ions (Na+, K+, Ca2+, Mg2+, Fe3+, Cu2+ and Zn2+) in the coagulating and water baths generated during the spinning process using ionic liquids (ILs) as solvent seriously affects the strength and textile performance of regenerated cellulose fibers, and make a huge challenge for the recycling and reuse of ILs. In this work, a ...

Alanine (Ala), regarded as the building block for protein synthesis, has been widely used in the field of food processing, pharmaceutical, and bio-based plastic industries. Containing plenty of oxygenic functional groups, biomass-derived chemicals are proper for Ala synthesis in an economic and green way via amination. In this work, lactic acid (LA...

Hogweed multiplies rapidly and gains a large volume of phytomass during the growing season, which allows us to consider the mature biomass of hogweed as a raw material for cellulose production. The aim of the work is to obtain cellulose from lignified stems of hogweed by an oxidative-organosolvent method and study its properties. Raw materials in t...

The catalytic activity of intrinsic alkali and alkaline earth metals (AAEM) in biomass has been usually considered as anegative factor affecting the fast pyrolysis of biomass. Herein, thisnegative factor was turned into a positive one using 0.4%H2SO4impregnation of pinewood, which can achieve the directionalpyrolysis of pinewood into levoglucosan a...

Both alkaline organosolv and formaldehyde stabilization pretreatment can yield high-quality lignin by preventing condensation. For the hydrogenolysis of the pretreated solid residues, the highest yield of C2-C4 chemicals was 66.8% under alkaline organosolv pretreatment for 60 min. Specifically, the crimped fibers and residual lignin and hemicellulo...

The dual regulation of water on lignin in ionic liquids was studied at the molecular level by molecular dynamics simulation. The simulation results show that a small amount of water will destroy the ion association in ionic liquids, that is, it will produce more free anions and cations. The free ions around lignin are conducive to the dissolution o...
