| 摘 要： | 在非程序升温单桩色谱仪上，采用双柱温法对ＣＯ／ＣＯ２加氢反应混合物进行在线分析，设置条件为３ｍ长的色谱柱ＧＤＸ－４０３，柱前压和检测温度固定不变，氢气为载气，ＴＣＤ为检测器，结果表明：在柱温３１３Ｋ，可以分析ＣＯ、ＣＨ４、ＣＯ２。在柱温３６８Ｋ，可以分析Ｈ２Ｏ和甲醇。通过计算反应前后２组物质浓度的变化，可以快速、准确评价催化剂的活性和选择性。

| Abstract: | On-line GC analysis of hydrogenation mixture of CO/CO2, with two column-temperature(CT), and one-column chromatograph without temperature-programmed device were reported. A 3m-long stainless column packed with GDX-403 and pre-column pressure and detection temperature were of 0.04 MPa and 373K, respectively, hydrogen was used as a carrier gas, and TCD for the detector. CO, CO2 and CH4 (group 1) were analysed at CT of 313K, and H2O and CH3OH (group 2)were analysed at CT of 368K. |
