The amount of resistant residual phase lignin is reduced by higher levels of hydroxide and lower amounts of dead load in the white liquor. This may indicate oxidative degradation, which produces peroxides and discoloration. The kraft process also known as kraft pulping or sulfate process is a process for conversion of wood into wood pulp, which consists of almost pure cellulose fibers, the main component of paper.
Both reactions promote lignin fragmentation and lignin solubilization, making the hydroxide ion a vital part in the removal of lignin.
Paper presented at the 1994 Stock Prep Short Course, Apr. Broaden awareness of how one part of the process impacts other operations• Both fourdriniers were replaced too, and the dry ends rebuilt. As a consequence, higher ionic strength will give an accumulation of lignin in the fibre wall, whereas a lower ionic strength would allow lignin to be leached out Sixta et al.

Get started on your summer recipes with a little inspiration from Kraft. The paper from western mills lost about twice as much brightness as that from eastern mills.
Also the yield is improved by lowering the temperature, as the rate of the peeling reaction is decreased as well Nieminen et al. The defibration point or fibre liberation point for conventional kraft cooking CK and extended impregnation kraft cooking EIC of eucalyptus Wedin et al.
In research, the kinetics of kraft pulping have been studied by constant-composition cooking.
Hundreds of illustrations, charts, and tables help the reader grasp the concepts being presented.
For hardwood, the boundaries are even more limited.
