Biorefineries, especially lignocellulosic feedstock biorefineries may play a major role for sustainable production in the future. In the presented work, findings of four separate studies were combined. These experimental and process simulation works included one study regarding the production of organosolv liquors to investigate lignin and carbohydrate solubilization and the precipitation of lignins,...
The performance of five polymeric nanofiltration and tight ultrafiltration membranes was investigated during separation of hemicellulose from process liquors containing 200 g/l sodium hydroxide. The effect of pressure and temperature on flux and retention was determined to enable optimization of operating conditions. Retention behavior was further elucidated by calculating retention as a function...
