Kraft Cooking with SAQ® Suitable for ECF Breaching
JAPAN TAPPI JOURNAL, 2003 SAQ® has been used as a cooking additive in many KP mills. This process is known as “Quinone Cooking”. In this paper, some new applications of SAQ®'s functions are proposed when ECF bleaching process is introduced in pulp mills.First, the effect of SAQ®, which decreases bleaching load keeping pulp yield and strength by lowering Kappa number, is ...

Mokuzai Gakkaishi, 2007 修正クラフト・キノン蒸解において，広葉樹材パルプの収率を向上させる最適化条件について検討した。そのために，まず実験室レベルで修正クラフト蒸解法を再現できる研究用の木材蒸解装置を開発した。これを用いて，修正蒸解工程に 1,4-ジヒドロ-9,10-ジヒドロキシアントラセンのナトリウム塩（SAQ）を添加する方法について検討したところ，蒸解途中で一部の黒液を白液と交換することによってパルプのカッパー価を下げることができること，SAQのパルプ収率向上効果は，SAQを蒸解初期に一括して添加する場合に分割添加する場合よりも大きいこと，この効果は，蒸解初期の白液添加比率を30～70％とする条件で白液を分割して添加する場合には，白液を一括して添加する場合と同等以上であること，また ...
