Porous carbons were obtained from rice husk using two different chemical activation methods and they were investigated as supercapacitors.Their properties were studied using X-ray photoelectron spectroscopy,thermal analysis,potentiometric titration,and ni

为解决焦炉煤气制LNG、甲醇等项目中预加氢、一级加氢、二级加氢样品中硫化物检测组分浓度差异大使得部分硫化物需要稀释进样的问题,采用价格低、普及性高的火焰光度检测器及填充柱气相色谱仪,通过减小定量环、改造信号放大组件、分段拟合等手段将直接进样检测焦炉煤气中形态硫的质量浓度检测范围拓宽至2.86~142.86 mg/m3。结果表明,在上述范围内一定浓度梯度进行复测,所得数据线性相关性高,满足相关标准要求。同时,该方法还能避免因焦炉煤气中各形态硫组分浓度差异大所造成的稀释后部分硫化物浓度过
