DEVELOPMENT OF A NOVEL EMPIRICAL MODEL TO ESTIMATE THE KRAFT PULP YIELD OF FAST-GROWING EUCALYPTUS
BioResources, 2012 In this study, several kraft pulps were produced by kraft pulping of fast-growing Eucalyptus with a wide range of cooking conditions. The dependences between pulp yields and some pulp properties, namely, kappa number, HexA contents, and cellulose ...

Effect of Sulfidity and Temperature on the Rate of the Delignification in Kraft Cooking
The Journal of the Society of Chemical Industry, Japan, 1963 硫化(NaSHまたはH2Sによる)およびスルホン化した材[S材]のソーダ蒸解およびアルカリ処理した材[A材]のクラフト蒸解を速度論的に研究し,クラフト蒸解における脱リグニンの機構について考察した。1)S材のソーダ蒸解における脱リグニンの速度は,蒸解の初期には非常に大きいが(クラフト蒸解のそれに匹敵する),蒸解の進行に応じて急激に減少する。また脱リグニンの活性化エネルギーは初期には小さいが(21～23kcal),末期には大きくなる(38～39kcal)。従って,S材のソーダ蒸解は,蒸解の初期にはクラフト蒸解の機構に類似しているが,末期にはアルカリによるイオウの脱離によってリグニンの縮合が増加して,漸次ソーダ蒸解の機構に近づくものと考えられる。2)クラフト蒸解においては ...
