褐煤生物溶煤优化试验研究 -

研究通过大浮沉试验、硝酸氧化、微波氧化等方法对抚顺褐煤进行改性;通过紫外、化学方法对真菌AH、云芝、金针菇以及裂褶进行了诱变,并对真菌AH在抚顺褐煤为唯一营养源的培养基中进行驯化。通过宏观观察和测定转化率发现,真菌AH对精煤含量高的、微波与硝酸氧化联合预处理的煤样具有较好的溶解效果;真菌AH经煤驯化后,其液体溶煤转化率高达45%。真菌AH可以直接利用抚顺褐煤,利用率最高可达18.22%;pH对溶煤也有重要的影响,碱性环境利于溶煤。 To improve properties of Fu Shun lignite,big vicissitude test,nitric acid microwave oxidations were used in this study.Fungi AH,Polyporus versicolor,Collybia velutipes and Schizophyllum commune were also treated by UV and chemicals.Especially,Fungi AH was inoculated on lignite,which is used as the only growth substrate,to improve its ability to dissolve Fushun Lignite.Fungi AH can easily dissolve fine lignite treated by nitric acid and microwave.After mutation,Fungi AH dissolved 45% of lignite treated by nitric acid and microwave.In addition,Fungi AH is able to grow on Fu Shun lignite with 18.22% utilizing ratio.Alkaline solution is benefit for bio-solubilization
