Lyocell Fibre Production Using NMMO – A Simulation-based Techno-Economic Analysis

BioResources, 2023
The demand for man-made cellulosic fibres is expected to grow in the future. One commercially-available concept to supply fibres is Lyocell manufacturing from dissolving wood pulps using N-Methylmorpholine N-oxide (NMMO) as the solvent.

Use of N-Methylmorpholine N-oxide (NMMO) pretreatment to enhance the bioconversion of lignocellulosic residues to methane. [PDF]

Biomass Convers Biorefin, 2022
Lignocellulosic residues (LRs) are one of the most abundant wastes produced worldwide. Nevertheless, unlocking the full energy potential from LRs for biofuel production is limited by their complex structure.

The bidirectional regulation mechanism of NMMO concentration change on cellulose dissolution and regeneration

Cellulose, 2023
Abstract The dissolution and regeneration process of cellulose molecules in NMMO aqueous solution was studied by molecular dynamics (MD) simulation. The effect of the concentration of NMMO aqueous solution on the structure of cellulose was discussed.

Direct production of regenerated cellulose films from pretreated corn stover using NMMO/water: Effects of pretreatment and crosslinking on film properties

Industrial Crops and Products
Although the fabrication of regenerated cellulose (RC) films from highly purified cellulose has been extensively studied, few efforts have explored their direct production from chemically pretreated biomass with varying lignin and xylan contents.
