Several additives have been used in research and on an
industrial scale to improve the pulp yield and to increase
the rate of delignification. One such additive is 1,4-
dihydro- 9,10-dihydroxyanthracene (DDA), also called soluble
anthraquinone. This chemical is widely used in Japan and
some other countries, especially with the...
A survey of the pulping literature indicated
that although the kinetics of the Kraft Pulping
process has been studied in detail , very few studies
have been reported for Alkaline Sulfite /
Anthraquinone (ASAQ) pulping process. There is no
existing rate model for this pulping process. Hence,
the objectives of...
