采用微波辅助碱处理的方法，从阔叶木硫酸盐浆中分离半纤维素和纤维素。在50 ℃和80 ℃下，微波和碱处理的半纤维素产率分别为9.25%和12.05%。相应地，所得纸浆纤维呈现出增加的纤维素含量，这对于制造溶解纸浆是期望的。此外，还研究了机械磨浆预处理后微波和碱处理对半纤维素和纤维素分离的影响。
In this study, the microwave was employed during the alkaline treatment process, in order to separate the hemicelluloses and cellulose from a delignified hardwood kraft pulp. In relation to hemicelluloses yield, the integrated microwave and alkaline treatment resulted in 9.25% and 12.05% at 50 degrees C and 80 degrees C, respectively. Correspondingly, the resultant pulp fibers presented the increased cellulose content, which was desirable for manufacturing dissolving pulp. Additionally, the effect from mechanical refining pretreatment followed microwave and alkaline treatment, on the separation of hemicelluloses and cellulose, was also investigated.
