Abstract

Abstract: The qualitative and quantitative of sulfur forms in Middle East mixed crude oil AR were analyzed in a fixedbed hydrogenation reactor. The results illustrated that the total sulfur in hydrotreated residue reduced gradually with the depth of hydrotreating. 83.22% of sulfur in the residue was removed. Distribution of sulfur content in feed and products was increased with the increasing of temperature. Ultimately, in distillate(<350 ℃), sulfide sulfur and a majority of benzothiophenes were removed. Although the influence of steric hindrance existed, most of dibenzothiophenes was also removed.

摘要： 对于中东混合原油常渣原料油在固定床连续加氢反应装置中的硫进行了定性和定量分析。结果表明, 经过固定床连续加氢处理后, 含硫化合物的含量随着加氢深度的增加明显降低, 脱除效果明显, 最终脱除率达到 8 3. 2 2%; 硫含量在原料油和生成油中的分布规律是随着温度的升高而增大; 最终得到的生成油<3 5 0℃馏分中的硫醚硫全部脱除, 苯并噻吩基本上脱除完全, 空间位阻大的二苯并噻吩类含硫化合物也大部分被脱除。
