在硫酸盐法中加甲醇降低硫化度

Sulfidity Reduction in a Kraft Process by adding methanol

在硫酸盐法中加w=6.3%甲醇,硫化度降低18%,或者加w=12.6%甲醇,硫化度降低33%,硫酸盐-甲醇法增加脱木素速率和提高得率,但纸浆强度稍受影响。

The sulfidity was reduced by 18% with the addition of 6.3% methanol in kraft process, or by 33% with the addition of 12.6% methanol. This kraft-methanol process improved the rate of delignification and increased the yield, but slightly affected the pulp strength.
