摘　　要：研究表明半纤维素酶Ｅ－Ａｎ－７６在桦木硫酸盐浆常规氯漂流程（ＣＥＨ）以及ＥＣＦ漂白流程（ＯＥＤＰ，ＯＤＥＰ）中都具有很好的漂白助剂作用，使化学漂剂用量降低而浆白度提高。The effects of hemicellase E An 76 in birch KP conventional bleaching process(CEH)and ECF bleaching process have been studied.Results show that E An 76 can be serevd as a good bleaching boosting both in CEH and ECF bleaching,which caused to reduce bleaching reagents and improve pulp final brighrness.Study of the mechanism of the E An 76 bleaching of kraft pulp shows that the reprecipitated or readsorbed xylan plays an important role in enzyme aided bleaching.
