资源简介：
Described is a method of kraft pulping in which a phenolic compound is added to the cooking step. The phenolic compound is added at a time point between about 5 minutes and about 120 minutes prior to completion of the cooking step. The presence of the phenolic compound increases the extent of delignification in the cooking step. Described is a method of kraft pulping in which a phenolic compound is added to the cooking step.

本发明公开了一种向蒸煮工序中投加酚类化合物的硫酸盐法制浆（kraft pulping）方法。该酚类化合物的投加时机为蒸煮工序完成前约5分钟至120分钟的区间内。酚类化合物的存在可提升蒸煮过程中的脱木素（delignification）程度。
