ABSTRACT This paper summarizes the review of developments in the area of ozone-based elemental chlorine free (ECF) and total chlorine free (TCF) bleaching of wood and non-wood pulps. Focused areas of review are reaction mechanism of ozone with carbohydrates and lignin, effect of process conditions maintained during ozone bleaching on pulp properties, effect of using different cellulose protectors, effect of alkaline extraction after ozone bleaching of pulps, effect of ozone bleaching on final bleached pulp properties, ECF and TCF bleaching sequences used along with ozone for of wood and non-wood pulps, and commercial scale utilization of ozone for pulp bleaching.

基于臭氧的纸浆漂白研究进展

摘要 本文总结了基于臭氧的无元素氯 (ECF) 和无总氯 (TCF) 木材和非木材纸浆漂白领域的发展综​​述。重点审查领域是臭氧与碳水化合物和木质素的反应机制，臭氧漂白过程中保持的工艺条件对纸浆性能的影响，使用不同纤维素保护剂的影响，纸浆臭氧漂白后碱提取的影响，臭氧漂白对最终漂白的影响纸浆特性、与臭氧一起用于木材和非木材纸浆的 ECF 和 TCF 漂白序列，以及臭氧在纸浆漂白中的商业规模利用。
