The article introduces a detailed model for carbohydrate chemistry in kraft pulping. This article is continuation to the modeling work carried out for hot water extraction and chemical pulp bleaching. The model includes galactoglucomannan, xylan, and cellulose acid–base equilibria, in addition to peeling, stopping, and alkaline hydrolysis reactions of the same carbohydrates, as well as hexenuronic acid formation and degradation reactions. The Arrhenius parameters were applied from the literature or regressed against experimental data in the present study. The model is very successful in predicting the experimental data of carbohydrate reactions during kraft pulping. Many features of the pulping‐related model can be applied to specific fractionation chemistry considerations. The detailed knowledge on carbohydrates composition at any stage of pulping gives possibility for further development of biorefinery cases based on kraft pulping, such as biofuel and chemicals production.

牛皮纸制浆化学的详细建模：碳水化合物反应

本文介绍了牛皮纸制浆中碳水化合物化学的详细模型。本文是对热水提取和化学纸浆漂白进行建模工作的延续。该模型包括半乳葡甘露聚糖，木聚糖和纤维素酸碱平衡，以及相同碳水化合物的剥离，终止和碱性水解反应，以及己糖醛酸的形成和降解反应。在本研究中，从文献中应用了Arrhenius参数或将其与实验数据进行了回归。该模型在预测牛皮纸制浆过程中碳水化合物反应的实验数据方面非常成功。制浆相关模型的许多功能都可以应用于特定的分馏化学考量。
