Oxygen-alkali delignification Kraft pulping in delignification of wood and non-wood is the most widely used process in the production of chemical pulps. As a successive process stage of the kraft pulping process, oxygen-alkali delignification (or oxygen delignification) 1-5 has acquired an important role lowering the residual lignin content in pulp prior to actual bleaching (see
