摘要
用过氧化氢作氧化剂对草浆黑液木质素进行化学加氢。最佳原料配比为：木质素：氨水：过氧化氢：水=1kg：25mol：10mL：4L，最佳反应条件为：反应温度100℃，反应时间60min，与用氧气作氧化剂相比具有不需耐压设备，反应时间缩短，反应温度降低，氨利用率提高的优点。
Ammonification of lignin from strew pulp black liquor using H2O2 as oxygenant was canied out. The optimal reaction conditions appeared to be as follows: lignin: H2O2: ammnia:water = 1kg: 25mol: 10mL: 4L, 60ndn at℃。Using H2O2 as oxygenan in the reaction required a sborter reaction time, a Lower reaction temperature, and a higher utilization of ammonia,
