A Study of the Feasibility of Using a Pulping Aid with Polysulfide Kraft Cooks [PDF]
, 1970 The purpose of this paper was to determine the feasibility of using a pulping aid with a polysulfide kraft cook. Since any change in an operation such as pulping must yield a product such that the quality is better or not appreciably reduced and at the ...

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 ...
