摘　　要：在30 mL连续流动固定床加氢试验装置上考察了气相H2S、NH3对柴油馏分芳烃加氢反应的影响。通过研究不同气相H2S、NH3含量下的柴油馏分芳烃加氢试验结果,建立了气相杂质含量和柴油馏分芳烃加氢反应表观速率常数之间的定量经验关系式,利用该关系式可以评估气相杂质对柴油馏分芳烃加氢反应的影响。The influence of H2S and NH3 on the activity of aromatics hydrogenation over sulfidized hydrotreating catalyst was investigated in a 30ml trickle-bed reactor using diesel fuel feedstock containing various dosages of carbonyl disulfide and butylamine. The test results showed that the aromatics hydrogenation reactions conducted in the presence of different contents of H2S and NH3 in gas phase could be written in the form of a pseudo-first-order reaction and the rate constant was obtained. An experiential correlation was established between the contents of H2S and NH3 and the rate constants of the aromatics hydrogenation reactions. This experiential correlation could be used to predict the effects of H2S and NH3 on the aromatics hydrogenation during the diesel fuel hydrotreating process.
