    摘要： A selective mid-distillate hydrotreating process is provided for production of hydrocarbon fuels with an ultra-low level of sulfur in which the initial hydrocarbon feedstock is introduced into to an aromatic extraction zone to produce an aromatic-lean fraction and an aromatic-rich fraction, which contain different classes of organosulfur compounds having different reactivities when subjected to hydrotreating reactions. The aromatic-lean fraction contains primarily labile heteroatom-containing compounds, and is passed to a first hydrotreating zone operating under mild conditions to remove the sulfur heteroatom from organosulfur hydrocarbon compounds. The aromatic-rich fraction contains primarily refractory heteroatom-containing compounds, including aromatic molecules such as certain benzothiophenes (e.g., long chain alkylated benzothiophenes), dibenzothiophene and alkyl derivatives, such as sterically hindered 4,6-dimethyldibenzothiophene, and is passed to a hydrotreating zone operating under relatively severe conditions to remove the heteroatom from sterically hindered refractory compounds.

    摘要翻译： 提供选择性中间馏分加氢处理方法用于生产具有超低硫含量的烃燃料，其中初始烃原料被引入芳族萃取区以产生贫芳烃馏分和富芳烃馏分， 其中含有不同种类的当加氢处理反应时具有不同反应性的有机硫化合物。 贫芳烃馏分主要含有不稳定的含杂原子的化合物，并且通过第一加氢处理区，在温和条件下操作以从有机硫化烃化合物中除去硫杂原子。 富含芳烃的馏分主要含有难处理的含杂原子的化合物，包括芳族分子如某些苯并噻吩（例如长链烷基化苯并噻吩），二苯并噻吩和烷基衍生物如空间位阻的4,6-二甲基二苯并噻吩，并且通过加氢处理 该区域在相对苛刻的条件下运行以从空间位阻难熔化合物中除去杂原子。
