【摘要】 采用TXS-Ⅱ硫分析仪对褐煤提质过程中的低温热解气进行含硫化合物定量分析研究,结果表明:(1)将气样通过脱硫剂脱除高浓度的H2S和COS之后再进行定量,因脱硫剂吸收有机含硫化合物,测定结果偏小;(2)制备了4种新的色谱分离柱,考查了这些色谱柱对有机含硫化合物的分离效果,最终建立了简便、准确检测低温热解气中含硫化合物的气相色谱分析方法,利用该方法分别对3种褐煤的低温热解过程中的气体进行了含硫化合物分析,为低温热解气的脱硫提供了依据。更多还原

【Abstract】 Using TXS-Ⅱ sulfur analyzer quantitatively analyzed the sulfur compounds in low temperature carbonization gas.The result showed that the method of eliminating H2S and COS of high concentration by desulfurizer and using TCP column to analyze the compositions of sulfur compounds by quantitative analysis,leads to a smaller measured value,because the desulfurizer will absorb some organic sulfur.Four different chromatographic columns were made to check their effects in desulfurization.After a series of exploration,a gas chromatography analysis method of simplicity and accuracy to determine the sulfur compounds in low temperature carbonization gas was established.Besides,the sulfur compounds in low temperature carbonization gas of different brown coal were analyzed by this method,providing a data base for desulfurization of pyrolysis gas.更多还原
