摘要： Knot rejects from chemical pulping processes are subjected to acid hydrolysis or an enzymatic hydrolysis treatment. The resultant hydrolysate is enriched with glucose, representing a value-added raw material for products using hexoses. The residue, separated from the said hydrolysate after the acid hydrolysis or enzyme treatment, consists of mainly knots or chips. The residue has a much improved aesthetic appearance which can be readily used as value-added raw materials for mulch or similar applications. The residue could also be extracted to obtain high value antioxidants and other nutraceutical chemicals such as lignans or can be utilized according to currently known practices including recooking, burning and depositing.

摘要： Final chlorine dioxide bleaching of lignocellulosic materials is most effective at a near-neutral pH but present industrial practice typically targets a final pH of between 3.5 and 4.0 because of the difficulty in achieving and maintaining near-neutral pH cost effectively. The in situ formation of bicarbonate before the addition of chlorine dioxide provides a way of maintaining the required near-neutral pH. Near-neutral final chlorine dioxide bleaching also produces a bleached pulp that is in a state that responds more effectively to fluorescent whitening or optical brightening agents.
摘要翻译： 木质纤维素材料的最终二氧化氯漂白在近中性pH下是最有效的，但由于难以有效地实现和维持近中性pH的成本，因此目前的工业实践通常将最终pH值定在3.5和4.0之间。 在添加二氧化氯之前，原位形成碳酸氢盐提供了维持所需的近中性pH值的方式。 近中性的最终二氧化氯漂白还产生漂白纸浆，其处于对荧光增白剂或荧光增白剂更有效响应的状态。
