摘要
利用产碱假单胞菌、施氏假单胞菌、铜绿假单胞菌和粗毛栓菌4种微生物对内蒙古褐煤进行溶煤实验,探索了煤样粒度、氧化程度、溶煤时间和溶煤方式等因素对溶煤率的影响,并对溶煤产物进行了红外光谱(IR)、紫外光谱(UV-VIS)和气相色谱-质谱联用(GC/MS)分析。结果发现,当采用煤样粒度为0.074-0.125mm、氧化程度为10 mol/L、溶煤时间为14天和摇瓶培养的方式进行溶煤时效果较好,其中,铜绿假单胞菌溶煤率最高,达62.61%。IR分析结果显示,溶煤后残煤红外光谱图与氧化煤红外光谱图相比羟基振动峰增强,芳烃结构振动峰减弱;UV-VIS分析结果显示,溶煤产物的主要成分为苯酚衍生物、醛类、醚类化合物;GC/MS分析结果显示,氧化煤经过微生物溶解以后,其结构发生变化,部分溶解为低分子量化合物。
Four kinds of microorganism are used to biosolubilise Inner Mongolia lignite.The factors influencing the percentage of biosolubilization,including grain size of coal sample,degree of oxidation,time of biosolubilising coal and the mode of biosolubilising coal are investigated.The coal biosolubilization products are analyzed by UV-VIS,IR spectrum and GC/MS.The results show that the percentage of biosolubilization is better when the coal sample size is 0.074-0.125 mm,10 mol/L nitric acid oxidized,time is 14 days and shaking culture is chosen,in which Pseudomonas aeruginosa is the highest,even reach to 62.61%.And the structure of oxidized coal is degraded into low molecular weight compounds after the process of biosolubilization of coal.
