中文摘要：

为寻求合理白度、节省资源、节能减排的漂白途径，研究了有机酸玉米秸秆皮生物炼制浆（OABCSRP）的短流程碱处理一二氧化氯一二氧化氯（ED1D2）无元素氯（ECF）漂白特性。结果表明：碱处理对OABCSRP具有良好的脱木质素选择性，是后续二氧化氯（D）漂白的重要基础，在浆浓10．0％（质量分数）、温度70℃、时间1．5h和用碱量4．0％的条件下碱处理，可获得率为95．4％、脱木质素率23．5％、黏度115mPa·s、白度44．2％（ISO）的纸浆；在碱处理过程中浆料中木质素和碳水化合物中的酯键发生了水解；ECF短流程ED1D2在4．0％NaOH及总ClO2用量3．6％条件下，经ED。D2漂白后，可获积累得率为88．0％、黏度124mPa·s、白度74．7％（ISO）的优良纸浆。

英文摘要：

To obtain a bleaching process with a reasonable brightness, low consumption of fiber resource and energy, the bleaching properties of organic acid biorefinery corn stalk rind pulp （OABCSRP） by a short ECF bleaching process of ED1D2 were investigated in present study. The results indicates alkali extraction is high selective on delignification of OABCSRP, and the extraction is a foundation for next effective D1 D2 bleaching stages. A pulp with 95.4% yield, 23.5% delignification ratio, 115 mPa. s viscosity and 44.2% ISO brightness was obtained when pulp with 10.0% concentration was treated by 4.0% NaOH for 1.5 h at 70 ℃. Interesting findings revealed that the ester linkages between lignin and carbohydrate were hydrolyzed in the extraction process. The pulp with an accumulated yield 88.0%, 124 mPa· s and brightness 74.7% ISO respectively when 4. 0% NaOH and 3.6% ClO2 dosages were applied in ED, D2 bleaching. EDlD2 short bleaching process was suitable for OABCSRP bleaching to produce cultural papers.
