[ad_1] Delignification is the process of removing lignin from wood pulp to ensure paper brightness and clarity. The Kraft process and oxygen delignification are commonly used, with the former being more effective. Lignin is an essential element in wood structure but causes staining in papermaking. Delignification is a group of industrial processes in which lignin, […]
[ad_1] Delignification is the removal of lignin from plant tissue for papermaking. The Kraft process dissolves lignin with sodium hydroxide and sodium sulfide, producing brown stock. Bleaching removes residual lignin, but oxygen delignification is a newer, more efficient process. Lignin is being researched for its potential in biofuel production, and scientists are studying microorganisms and […]
