| 中文摘要: |
| 以熟石灰、Al(OH)3及NaOH为除硅剂，在芦苇碱法制浆过程中进行除硅蒸煮，同时采用响应曲面分析法研究了熟石灰用量、Al(OH)3用量以及NaOH用量对除硅率的影响。结果表明，熟石灰用量2.70%、Al(OH)3用量0.57%、NaOH用量8.0%,在此条件下,除硅率达到95.92%。 |
| Abstract: |
| The desilicating process during reed pulping was described and the effect of the desilicating agents such as white lime and Al(OH)3 on black liquor hardness was discussed. The effect of the dosages of white lime, Al(OH)3 and NaOH on the desilicating rate was studied by means of response surface methodology, and their optimal dosages were as follows: white lime, Al(OH)3 and NaOH were 2.70%, 0.57% and 8.0%, respectively, and the desilicating rate reached 95.9%. Meanwhile, black liquor hardness was not affected by the addition of the desilicating agent． |
