Changes in the lignin-carbohydrate complex in softwood kraft pulp during kraft and oxygen delignification

Three kraft pulps in the kappa number range between 50 and 20 and the same pulps oxygen-delignified to similar lignin contents (kappa approximately 6) were analyzed for lignin-carbohydrate complexes (LCC) by a method based on selective enzymatic hydrolysis of the cellulose, and quantitative fractionation of the LCC...

Keywords: bleachability, kappa number, kraft pulping, lignin-carbohydrate complex (LCC), oxygen delignification, residual lignin, specific absorptivity
