Delignification - an overview | ScienceDirect Topics
WebDelignification, the process of extracting lignin from plant sources, can be done using a variety of methods. Its aim is the disintegration of the lignocellulosic structure into its fibrous components [20]. The delignification processes can be divided into two major classes: chemical and solvent processes.

Delignification - an overview | ScienceDirect Topics
WebThe delignification occurs in three stages: initial, main and residual. The initial stage is observed at low temperatures where 20%–25% of the lignin can be dissolved. The main stage is appreciated at temperatures above 140°C, when delignification speed is increased significantly by temperature and concentrations of hydroxide and sodium ...
Insights into delignification behavior using aqueous
WebOct 8, 2020 · Abstract. Exploring an efficient delignification technique is imperative for further advance on biorefinery, together with elucidation on affecting factors and mechanism of delignification. Biomass fractionation using the aqueous p -toluenesulfonic acid ( p -TsOH) changed tremendously with biomass species.
