摘　　要：介绍红麻全秆硫酸盐法间歇蒸煮的实验室研究及中试生产试验。结果表明,优化的红麻全秆硫酸盐法制浆工艺条件为:用碱量18%(Na2O计),硫化度25%,温度165℃,保温时间2h。生产试验结果与实验室结果相吻合,红麻全秆可以在常规的草类制浆线上正常生产。生产纸浆的粗浆得率为45%,卡伯值为22。此外,蒸煮黑液的碱回收是可行的。The experiments and production of batch kraft cooking of whole stalk kenaf was discussed. The results showed that the optimal process conditions were as follows： alkaline charge 18%（Na2O）, sulfidity 25%, temperature 165℃, retention time was 2h. The production results accorded with the experimental results and it was possible to produce kenaf kraft pulp on the common production line for nonwood fiber. The yield of produced pulp was 45.0%, kappa number was 22.0, and the alkaline recovery of black liquor was feasible.
