Kraft Process-Formation of Secoisolariciresinol Structures and Incorporation of Fatty Acids in Kraft Lignin. [PDF]
The complex chemical structure and the fact that many areas in pulping and lignin chemistry still remain unresolved are challenges associated with exploiting lignin. In this study, we address questions regarding the formation and chemical nature of the insoluble residual lignin, the presence of fatty acids in kraft lignin, and the origin of ...

Bleaching of radiata pine Kraft pulp with the EnZone process
Abstract Oxygen delignified Kraft pulps from radiata pine were treated with xylanase in the presence of a quelating agent prior to their chemical bleaching with the sequences WZEOPP, EPWZP and EOPWZP. Enzymes tested included Cartazyme from Sandoz, Ecopulp from Alko-ICI, Irgazyme 40 from Ciba-Genencor and Pulpzyme HB from Novo Nordisk.

The Kraft process consists of the cooking process and the bleaching process mainly. In Kraft process, the weakest point is the low of the yield of pulp in the cooking process. The kinds of quinone derivatives or polysulfide derivatives are widely used as cooking agents to improve it.“Cooking Accelerator” is the agent to accelerate the function that ...
