| 摘 要： | 对木聚糖酶预处理的麦草碱法化学机械制浆与漂白过程中木聚糖酶处理的效果进行了研究。结果表明,在制浆与漂白前酶预处理段较佳的木聚糖酶用量分别为 15 IU/g 和 12 IU/g,酶预处理时间同为 120 min。利用木聚糖酶预处理与 H2O2漂白相结合的 XP5aP5a 多段漂白程序,可以获得 74.6%ISO白度的麦草生物化机浆。

| Abstract: | Effect of xylanase pretreatment prior to soda treatment during chemi-mechanical pulping of wheat straw and hydrogen peroxide bleaching of wheat straw bio-chemimechanical pulp was studied. The results showed that suitable xylanase dosage of pretreatment wheat straw was 15 IU/g (on oven dry wheat straw), and the suitable xylanase dosage of pretreatment wheat straw chemi-mechanical pulp was 12 IU/g (on oven dry pulp). Pretreatment time with xylanase was 120 min during chemi-mechanical pulping, and about the same during hydrogen peroxide bleaching of wheat straw bio-chemimechanical pulp that 74.6% ISO brightness of wheat straw bio-chemimechanical pulp could be achieved by XP5aP5a bleaching sequences. |
