摘要：采用高温裂解燃烧/离子色谱法建立了测定煤直接液化产品微量氯含量分析方法。样品在高温裂解燃烧炉燃烧,其中氯化合物生成HCl气体或Cl2,经水吸收形成含Cl-的水溶液,离子色谱测出水溶液中的Cl-含量,进而计算出样品中的氯含量。优化的测定条件:燃烧炉温度1300℃,燃烧时间10 min,载气流速1.5 mL/min,样品进样量为0.10～0.16 g。2种不同添加量加标样品的平均回收率为106.61%和94.82%,分析结果的相对标准偏差为3.24%和0.18%。通过对多种煤直接液化产品氯含量分析,获得了煤液化产品中氯含量分布信息。
An analytical method for determination of trace chlorine in coal direct liquefaction products was established by the combination of high-temperature cracking combustion and ion chromatography. When the samples burn in high-temperature cracking combustion furance, the chlorinated compounds in samples transform into HC1 or C12, which were absorbed by water, then formed chloride solution. Analyse Cl^- content using ion chromatography and determine chlorine content in sample. The optimized determination condition is that, the combustion furnace temperature is 1300 ℃ ,the burning time is 10 minutes, the carrier gas flow rate is 1.5 mL/min, the sample mass range from 0. 10 g to 0. 16 g. The average recovery rate for chlorine are 106.61 percent and 94. 82 percent. The RSD are 3.24 percent and 0. 18 percent. Based on the analysis of direct coal liquefaction products chlorine content, obtain distribution information of chlorine content in coal liquefaction products.
