Chip-Handling and Kraft Pulping.
JAPAN TAPPI JOURNAL, 1996 パルプ原材料の96%を占めるチップの現状と購入チップの受け入れ設備及び貯蔵施設に触れた後, KP蒸解反応と連続蒸解設備の改良について, 反応速度論の立場から解説した。脱リグニン反応速度と炭水化物の崩壊反応速度をチップ厚さの影響なども含め説明し, 時間, 温度, アルカリ濃度, 硫化度及びチップ厚さの5因子を入れた蒸解反応速度式をアルレニウスの式に基づいた実験式として紹介した。さらに蒸解の目的がパルプ成分である炭水化物をできるだけ多く残し, リグニンの残留量を少なくすることから.反応が選択的になり得るための望ましい蒸解反応条件を探るために蒸解反応の選択性とシミュレーションによる最適化を解説した。すなわち, 得られた実験式に各種蒸解条件を入れて数値計算し ...

From Hemp Bast to Lyocell Fiber: Sustainable Process Optimization for Lyocell‐Grade Dissolving Pulp
Journal of Applied Polymer Science, Volume 143, Issue 16, April 20, 2026.This study presents a sustainable method to produce lyocell‐grade dissolving pulp from Canadian hemp bast fibers. A simplified alkali‐chelation‐bleaching process, free from sulfur and chlorine, yielded high α‐cellulose pulp with low lignin and hemicellulose content. The pulp was successfully spun into continuous hemp‐based lyocell fibers, demonstrating

Revisiting acidulation for tall oil and lignin manufacturing
The Canadian Journal of Chemical Engineering, Volume 104, Issue 4, Page 1677-1691, April 2026.Abstract Tall oil is a byproduct of the kraft pulping process when softwood is used as raw material. As the production of softwood‐based pulp is in high demand, the optimization of the tall oil production process needs to be revisited to ensure the highest quality and quantity of tall oil manufacturing. In this work, the process for tall oil production
