Preparation of Acetate Grade Pulp from Birch by Alkali Preimpregnation Kraft Process
In this study, alkali preimpregnation was proved to be an pretreatment that could remove the hemicellulose effectively. Both the concentration of NaOH and the preimpregnation time were investigated. The optimum amount of NaOH 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-E-Q-P-A bleaching sequence.
