以改性氧化铝为载体,采用等体积浸渍法负载活性金属组分W和Ni,制备出润滑油加氢催化剂CAT-A,分别对其进行扩孔、酸改性处理,制得相应催化剂CAT-B,CAT-C。利用X射线粉末衍射、N2吸附-脱附、氨气程序升温脱附、扫描电子显微镜等分析手段,对所制备催化剂进行了表征;同时,以减四线馏分油为原料,在中试固定床加氢装置上,对催化剂进行了加氢性能评价。结果表明:扩孔处理使CAT-A催化剂上的可接触活性位点增加,有利于深度脱硫脱氮,酸改性则有利于硫化物在高温下的裂化脱除;在反应温度为390 ℃时,CAT-B催化剂加氢反应脱硫率、脱氮率分别为99.5%,99.7%,不低于280 ℃馏分收率(质量分数,下同)为94%, CAT-C催化剂的上述各值依次为99.6%,99.8%,90%。
- Abstract:
-
The lubricating oil hydrogenation catalyst CAT-A was prepared with modified alumina as carrier, isovolumic impregnation method loaded W and Ni as active metal components. Then catalysts CAT-B and CAT-C were prepared by pore enlargement and acid modification respectively. These catalysts were characterized by the methods of X-ray powder diffraction,N2 adsorption-desorption, ammonia temperature-programmed desorption, electron transmission microscopy,and the hydrogenation performances of these catalysts were evaluated in a pilot-scale fixed bed hydrogenation device with the vacuum cut 4th distillate oil as raw material. The results showed that the accessible active sites on CAT-A was increased through pore enlargement treatment, which was beneficial to deep desulfurization and denitrification, and acid modification was beneficial to the cracking removal of sulfide at high temperature. At the reaction temperature 390 ℃, the desulfurization rate and denitrification rate of catalyst CAT-B was 99.5% and 99.7% respectively, and the yield of distillates not lower than 280 ℃ was 94%. The above parameters of catalyst CAT-C was 99.6%, 99.8% and 90% in sequence.
