煤生物转化产物作为水煤浆添加剂试验研究

APPLICATION OF BIOCONVERSION PRODUCTS OF COAL IN PRODUCING COAL-MATER-MIXTURE

摘要: 本项研究通过培育微生物菌种,作用于经硝酸处理的褐煤样,得到煤生物转化产物。用此水溶性产物作为添加剂制备出水煤浆,与加与不加常规添加剂的两种水煤浆进行粘度对比试验,从考察了煤生物转化产物制备的水煤浆流变特性。结果显示使用煤生物转化产物作为水煤浆添加剂能制备出优质水煤浆。

Abstract: In this research,the bioconvesion products have been obtained through the apptication of cultivation fungis to the lignite coal pre-treated with nitric acid.Based on the comparison of the viscosity of coal-water-mixture when additive is added and when it is not.The rheologic behavior of coal-water-mixture produced by bioconversion products has also been researched.
