选用黄孢原毛平革菌对义马煤进行了微生物降解试验,主要考察了硝酸、双氧水和超声波预处理对义马煤微生物溶解的影响.试验结果表明,煤样的预处理可以促进义马煤的微生物降解,硝酸预处理的效果最好,降解率提高了28.34%,并对义马煤原煤样及预处理煤样进行了工业分析和元素分析,煤质分析结果表明预处理是对义马煤的一种氧化方式,增加了煤样中的氧含量,更有利于微生物降解. 相似文献

用白腐菌脱除重庆高硫煤中硫的研究 总被引:19,自引:3,他引:16
首次将白腐菌应用于煤炭脱硫,并对其可行性、原理进行了摸索.通过正交试验研究了白腐菌在煤炭脱硫过程中细菌数量、煤浆浓度、煤粒度和预处理等各因素对其脱硫的影响,并筛选出各因素的最佳试验条件,在此基础上探讨了白腐菌脱硫的降解规律.实验结果表明,白腐菌煤炭脱硫是完全可行的,而且白腐菌脱硫速度较快,2d内可脱除煤中无机硫的5530%、全硫的4454%. 相似文献

Jurassic weak & non-stick coal in Hengshan of North Shaanxi Province was pretreated by the nitric acid. Then, it was biodegraded
by Phanerochaete chrysosporium. The biodegradation role of the white-rot fungus for coal is extremely significant. Orthogonal test demonstrate that liquefied
time, liquefaction temperature and the amount of fungus liquids etc. are the main factors affecting the coal biodegradation
rate. The best technical condition of the coal biological liquefaction was got. Comparing the coal sample before biodegradation
with that after biodegradation, it is found that the ash of the coal residue after biodegradation reduces significantly, H
and O contents increase, C and N contents decrease. The biodegradation change the coal macromolecular structure.
