摘　　要：选择质量分数ｗ（苯）１２２８％，ｗ（甲苯）３３２％，ｗ（芳烃）１５６％的６＃抽提溶剂油为原料，应用镍铝催化剂在１０ｍＬ高压加氢固定床微反气相色谱联合装置上进行催化加氢脱芳烃的研究，考察了不同操作条件下６＃抽提溶剂油催化加氢脱芳烃的效果。在反应压力０５ＭＰａ，氢油体积比７０∶１，反应温度１３０℃，空速１０ｈ－１的条件下，６＃抽提溶剂油催化加氢脱芳烃的效果较好，加氢后油中ｗ（总芳烃）可降至００５％，符合中国石油天然气总公司科技局提出的油中ｗ（芳烃）不大于０１０％的要求。The 6 # extraction solvent oil contains benzene 12.28, toluene 3.32, and total aromatic hydrocarbons 15.60%. Hydrodearomatization of the feed was carried out on a 10 ml scale fixed bed microreactor chromatography unit over a Ni Al catalyst. Effects of reaction conditions on the dearomatization were investigated. The preferred results were obtained at reaction condition of 130 ℃, 0 5 MPa,SV=1 0 h -1 and H 2/oil volumeric ratio of 70∶1. At this condition, the hydrogenated oil contains less than 0 05% aromatic hydrocarbons,which meets the requirment of 6 #extraction solvent oil for aromatic hydrocarbons content of less than 0 1%.
