Oxygen Delignification of Acid Sulfite and Bisulfite Softwood Pulps
BioResources, 2015 This study discusses alternatives for the production of sulfite pulps cooked to high kappa numbers, and a subsequent oxygen treatment by using the same cation in the cooking and in the oxygen stages. Magnesium was used as a cation during both the cooking

Delignification Kinetics of Corn Stover with Aqueous Ammonia Soaking Pretreatment
BioResources, 2016 Soaking aqueous ammonia (SAA) pretreatment of corn stover was carried out at three temperatures (30, 50, and 70 ºC) and three concentrations of ammonia solution (5, 15, and 25 wt.%). The delignification kinetic model, based on three first-order reactions,
