摘　　要：以环烷基油常三线和减二线馏分油为原料,采用柴油加氢催化剂进行加氢试验,考察反应温度对芳烃脱除效果的影响。结果表明,在反应压力7 MPa、质量空速1.0 h^(-1)、氢油体积比500∶1的条件下,常三线馏分油在反应温度340℃时加氢处理的产品具有开发《橡胶增塑剂芳香基矿物油》(GB T 33322—2016)A1004产品的可行性,减二线馏分油在反应温度350℃时加氢处理的产品具有开发GB T 33322—2016标准A0709产品的可行性。加氢后产品中的大部分强致癌芳烃得到了有效脱除,仅剩五环芳烃苯并(e)芘,其分子结构空间位阻大,难以加氢饱和,是影响8种特定多环芳烃含量的主要组分。采用该中压加氢处理工艺可以直接制备环保橡胶增塑剂,提高精制油收率。Hydrogenation experiments were carried out using diesel hydrogenation catalyst to investigate the effect of reaction temperature on hydrogenation efficiency with naphthenic distillate AGO3 and VGO2 as raw materials.The results showed that under the conditions of a reaction pressure of 7 MPa,a mass space velocity of 1.0 h^(-1),a hydrogen-oil volume ratio of 500∶1,the product with AGO3 hydrotreating at reaction temperature of 340℃has the feasibility of developing“rubber plasticizer aromatic base mineral oil(GB T 33322—2016)”A1004 product.It is feasible to develop A0709 product for the product with VGO2 hydrotreating at the reaction temperature of 350℃.After hydrogenation,most of the forced carcinogenic aromatics in the product are effectively removed,and only benzo(e)pyrene is left,which is a major component affecting the content of eight specific aromatics because of its high steric hindrance and difficult to hydrogenate.The medium pressure hydrotreating process can directly prepare environmentally friendly rubber plasticizer and improve the yield of refined oil.
