Although a number of treatment methods can be used to separate cellulose and lignin components from biomass, aqueous alkaline treatment methods are dominant. Typically, the cellulose is precipitated from solution, and the lignin ends up in the highly

Kraft lignin was fractionated by molecular weight (MW), using CO2-expanded solutions of acetic acid/water in a 90/10 wt/wt ratio. In particular, as CO2 pressures were increased from 7 bar to 48 bar, expanding the liquid-solvent phase and reducing its
