02/2005 | Holzforschung, Walter de GruyterElucidating carboxylic acid profiles for extended oxygen delignification of high-kappa softwood kraft pulps
Two laboratory high-lignin-content softwood (SW) kraft pulps with kappa values of 48.0 and 49.5, prepared by cooking at high and low active alkali (AA), were used for the study of fiber charge development during two-stage oxygen delignification with inter-stage washing (OwO)...
