摘要
选择神府煤和热带假丝酵母菌为研究对象,硝酸预处理原煤获得硝化煤,并对硝化煤进行微生物溶解,获得残煤和溶煤产物,分别考察了原煤、硝化煤、残煤和溶煤产物四类煤样的IR谱图、XRD谱图和TG-DTG曲线。分析结果显示,原煤、硝化煤、残煤和溶煤产物的红外谱图基本一致,其芳香层片间距离d_(002)分别为0.37041 nm,0.38674 nm,0.40952 nm和0.42064 nm,热分解过程总失重率分别为32.21%,41.10%,48.76%和52.68%,表明硝酸和热带假丝酵母菌使煤样的大分子有序程度逐渐降低,"煤晶核"不断减小,热稳定性相应降低,低温区挥发性物质增多。
Shenfu coal and Candida tropicalis were chosen as the research object.The raw coal was pretreated by nitric acid and then solubilized by Candida tropicalis.The four kinds of coal samples raw coal,oxidized coal,residual coal and biosolubilized products were examined by IR,XRD and TG-DTG.Analysis results show that the IR spectra of raw coal,oxidized coal,residual coal and products are in consistent with each other,and their inter-layer spacing are 0.37041 nm,0.38674 nm,0.40952 nm and 0.42064 nm,respectively,their total weightlessness rate of TG are 32.21%,41.10%,48.76% and 52.68%,this indicated that the treatment of nitric acid and Candida tropicalis result the macromolecules of coal less order,the crystal nucleus of coal constantly decreases,the thermal stability also corresponding reduced,and volatile substances at low temperature region increase.
