Chemistry of Kraft Pulping and Pulp Bleaching
JAPAN TAPPI JOURNAL, 2000 Chemistry of kraft pulp production was summarized from considering recent environmental plans. Levels of dioxins and chloroform emission in regulations were shown first, and then chemical feature of lignin, reactions of lignin and carbohydrates during kraft pulping, structure of residual lignin in pulp, reactions of chlorine and chlorinated chemicals ...

Effect of xylanase pretreatment on the kraft pulping of poplar [PDF]
BioResources, 2020 This study aimed to determine the influence of prehydrolysis of wood chips on the kraft pulping of Populus x euramericana. Optimum cooking conditions were determined by evaluating different alkali concentrations and cooking periods. Xylanase was used to hydrolyze chips before cooking.

The Canadian Journal of Chemical Engineering, EarlyView.Sodium alginate was modified with EDC/NHS for the immobilization of Yacon peel peroxidase, resulting in a novel biocatalyst for the oxidation of 2,4‐dichlorophenol. Abstract Yacon (Smallanthus sonchifolius) roots are emerging as an alternative source of peroxidase. This study aimed to extract, immobilize, and characterize the peroxidase from Yacon peel,
