A contribution to the modeling of kraft pulping
The Canadian Journal of Chemical Engineering, 1997AbstractThis paper presents a mathematical model for pulping that considers the effect of alkali diffusion and chemical reaction. An approximation for 3‐dimensional diffusion in wood chips is tested against pulping data. A method for predicting pulp viscosity is also presented.

Chemical aspects of kraft pulping
Wood Science and Technology, 1980Kraft pulping is interpreted in chemical terms on the basis of results from extensive qualitative and quantitative model experiments. In essence, the behavior of lignin is explained as a competition between degradation reactions, mainly involving aryl ether cleavage with participation of neighboring groups, and condensation reactions, comprising ...

Air pollution control in kraft pulp mills
American Industrial Hygiene Association Journal, 1978A patented gas scrubbing process, whereby the emissions of malodorous reduced sulphur compounds are effectively and economically reduced, is described. Stack gases are scrubbed with an alkaline suspension of activated carbon. Reduced sulphur compounds as well as sulphur oxides are converted to sodium salts which are subsequently recovered and utilized ...

The colouring matter in kraft pulp. --.
1939The colouring matter is the name applied to a coloured material believed to be present in chemical wood pulps and regarded, by workers in the field, to be of considerable importance in the bleaching of these pulps. In the production of a good quality white pulp from wood, two main steps are involved, namely the "cooking" of the wood, and the bleaching ...

Enzymes in bleaching of kraft pulp: Dissertation
1992Cellulose pulp produced by the kraft pulping process is the predominant raw material for production of paper. Although most of the wood lignin is removed during kraft pulping the residual brown coloured lignin must be removed and the brightness of the pulp increased in a multistage bleaching processes prior to paper production.
