摘要：

In this study, alkali preimpregnation was proved to be an pretreatment that could remove the hemicellulose effectively. Both the concentration of NaOII and the preimpregnation time were investigated. The optimum amount of MOH was 16% od wood in the kraft pulping process. Cooking with 0.05% AQ (anthraquinone) could avoid the reduce of cellulose. The physicochemical Parameters of acetate grade pulp can be achieved after the O-D-E-D-L-Q-P-A bleaching sequence.
