本文在使用国内兰州科海公司提供的一套模拟蒸馏分析软件的基础上,利用一根内装OV-101担体的非极性填充柱,实验探讨乙烯裂解用石脑油馏程的快速测定方法并评价了方法的重复性和再现性。实验结果表明,该法操作简单,11分钟内完成一个样品的分析,测定重复性好,相对标准偏差≤3%,再现性满足GB/T 6 5 3 6-2 0 1 0标准的要求,能实现快速检测石脑油馏程,可以替代手工蒸馏法。
Based on a set of simulated distillation analysis software provided by Lanzhou Kehai Company, a non-polar packed column packed with OV-101 carrier was used in this paper to explore the rapid determination method of naphtha distillation range for ethylene cracking The method was evaluated for reproducibility and reproducibility. The experimental results show that the method is easy to operate and the analysis of one sample is completed in 11 minutes. The repeatability is good and the relative standard deviation is less than or equal to 3%. The reproducibility meets the requirements of GB / T 6 5320-210 Rapid detection of naphtha distillation process, can replace manual distillation.
