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%。The desilicating process during reed pulping was described and the effect of the desilicating agents such as white lime and AI（OH） 3 on black liquor hardness was discussed. The effect of the dosages of white lime, AI（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, A1 （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.
