初步探讨一种将乙醇制浆和乙醇发酵相结合的生物制浆方法,乙醇发酵和草类原料预处理同步进行,在乙醇发酵过程中,利用发酵产物(乙醇、有机酸、盐类、二氧化碳和余热)对麦草进行预处理,用于分离木素和制备纸浆,经实验测得在蒸煮效果(细浆得率55%、卡伯值60)相同的条件下,经过预处理的秸秆制浆所需的蒸煮温度(165℃)要比未经过预处理的制浆温度(185℃)低20℃,保温时间少10min,有助于减少制浆成本,促进乙醇法制浆技术的推广,减少传统造纸企业的环境污染。
In this paper, a bio-pulping method combining ethanol pulping and ethanol fermentation was discussed. Ethanol fermentation and pretreatment of grass material were carried out synchronously. During the fermentation of ethanol, the fermentation products (ethanol, organic acids, salts, carbon dioxide and Waste heat) pretreatment of wheat straw for the separation of lignin and preparation of pulp, the experiment measured in the cooking effect (pulp yield 55%, kappa number 60) under the same conditions, pretreated straw pulping The required cooking temperature (165 ℃) is 20 ℃ lower than that of the pulp without pretreatment (185 ℃) and the holding time is less 10min, which can help to reduce the cost of pulp, promote the popularization of ethanol pulping and reduce the traditional Environmental pollution in papermaking enterprises.
