【摘要】 考察了在甲醇溶剂中 ,超声波辐射下煤中有机硫的脱除。结果表明 :煤中有机硫的脱除率随着碘甲烷用量和超声波辐射时间的增加而增加。根据红外光谱仪和气相色谱 质谱联用分析仪分析结果 ,被脱除的有机硫包括硫醚和二硫化物。应用此工艺从青海煤和伊朗煤中还可脱除噻吩形态的有机硫。更多还原

【Abstract】 Investigated was the removal of organic sulfur from coal in methyl alcohol solution under ultra sonic radiation. Results denoted that the organic sulfur removal rate was proportional to consumption of iodine methane and radiation time. From analyses, the removed organic sulfur included thio ether and disurfide. For Qinghai and Iran coals, the removed organic sulfur was in the form of thiophene.更多还原
