CORN STALK EXTENDED DELIGNIFICATION COOKING AND H2O2 BLEACHABILITY
By using extended delignification technique, corn stalk soda-anthraquinone pulp was cooked, with adding the preparation of different alkali header. The results of the study indicated that under the same dosage of anthraquinone, with the increase on the preparation of alkali header, KP number reduced at first, and then it stopped to be even. Under the same condition of KP number, the H2O2 bleachability was contrasted between the pulp with adsorbent lignin and that with rudimental lignin. It is found that, the pulp with adsorbent lignin was much easier to bleach with H2O2 than pulp with rudimental lignin. The result showed that dissolved lignin in black liquid would be reabsorbed to fiber again, and reabsorbed lignin in pulp was easier to bleach with hydrogen peroxide than the remnant.
