FHUDS-2催化剂用于镇海混合油深度加氢脱硫的研究

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6.4MPa,体积空速1.5h-1,氢油比500,反应温度360～370℃或者在反应温度360℃,氢分压6.4MPa,氢油比500,体积空速1.0～1.5h-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。...

Bibliography: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.
