| 摘要: |
| 在小试装置上,采用镇海混合油评价了工业催化剂FHUDS-2的深度加氢脱硫性能,同时考察了混合油中硫化物在FHUDS-2催化剂上的转化规律。结果 表明:4,6-二甲基二苯并噻吩类(4,6-DMDBTs)硫化合物在产品中所占比例逐渐提高,对反应温度敏感性低,是原料油中最难脱除的含硫化合物；FHUDS-2催化剂具有优异的深度及超深度加氢脱硫性能,在氢分压6.4 MPa,体积空速1.5 h-1,氢油比500,反应温度360~370 ℃或者在反应温度360 ℃,氢分压6.4 MPa,氢油比500,体积空速1.0 ~1.5 h-1条件下,都能生产出硫含量符合欧Ⅳ、欧Ⅴ排放标准的低硫和超低硫柴油。 |

| Abstract: |
| In the small-scale test apparatus, the deep hydrodesulfurization property of FHUDS-2 catalyst was evaluated by using Zhenhai mixed fuel. Additionally, the transformation mechanism of sulfides on the FHUDS-2 catalyst was studied . The results showed that 4,6-DMDBTs were the most difficult removal sulfide, and it has low sensitivity to temperature. The ratio of 4,6-DMDBTs increased gradually in product. FHUDS-2 catalyst has excellent performance of deep or ultra-deep hydrodesulfurization. Under the conditions of partial pressure of hydrogen 6.4 MPa, volume space velocity 1.5 h-1, volume ratio of hydrogen to oil 500, and reaction temperature 360~370 ℃ or reaction temperature 360 ℃, partial pressure of hydrogen 6.4 MPa, volume ratio of hydrogen to oil 500, and volume space velocity 1.0~1.5 h-1, FHUDS-2 catalyst could produce the deep and ultra-deep diesel fuel satisfying the European Ⅳ and European Ⅴ emission standards. |
