摘　　要：为了探讨碳酸氢铵-氨水联合活化法制备腐植酸铵工艺特点,本研究以新疆风化煤为原料,氨水和碳酸氢铵为活化剂,通过对活化条件进行单因素试验、正交试验确定了最佳的活化工艺。结果表明:活化温度80℃、投氨量20%、碳化度60%、水煤比2(g/g)时,活化率最高,腐植酸铵水溶性腐植酸含量17.62%。In order to explore the process characteristics of preparing ammonium humate using ammonium bicarbonate and ammonia water,in this study,weathered coal with low free humic acid content from Xinjiang was used as raw material,ammonia water and ammonium bicarbonate as activators,and the optimal activation process was determined by single factor experiments and orthogonal experiments.The results showed that the activation rate was highest at an activation temperature of 80℃,an ammonia dosage of 20%,a carbonization degree of 60%,and a water coal ratio of 2(g/g).The content of water-soluble humic acid in ammonium humate was 17.62%.
