摘　　要：为考察不同产地原料煤和酸煤比(质量比)对硝酸氧化降解原料煤制备硝基腐殖酸的氧化降解效果的影响,对东北褐煤、云南褐煤、新疆风化煤等3种原料煤开展了试验研究。结果表明:在相同的酸煤比等反应条件下,东北褐煤比云南褐煤、新疆风化煤更易于氧化;3种原料煤经硝酸氧化降解后,总腐殖酸和黄腐酸含量均得到大幅提高。采用硝酸氧化降解褐煤、风化煤制取硝基腐殖酸,不仅提高了低阶煤的利用率和附加值,还解决了腐殖酸行业高品质原料煤资源匮乏的问题。In order to investigate the influence of different raw coal and acid coal ratios(mass ratio)on the oxidative degradation effect of nitric acid on the preparation of nitrohumic acid from raw coal,experimental studies are conducted on three types of raw coal,namely Dongbei lignite,Yunnan lignite,and Xinjiang weathered coal.The results show that under the same reaction conditions such as acid coal ratio,Dongbei lignite is more prone to oxidation than Yunnan lignite and Xinjiang weathered coal.After nitric acid oxidation degradation of three types of raw coal,the total humic acid and fulvic acid content are significantly increased.The use of nitric acid oxidation to degrade lignite and weathered coal to produce nitrohumic acid not only improves the utilization rate and added value of low-grade coal,but also solves the problem of scarce high-quality raw coal resources in the humic acid industry.
