摘要
为更好发挥柴油超深度加氢脱硫(RTS)不同反应区域内不同类型催化剂的优势,在中型试验装置上考察了加氢反应活性高的Ni-Mo-W型催化剂、直接脱硫反应活性高的Co-Mo型催化剂和具有轻微加氢改质活性的Ni-W型催化剂的不同级配方式对柴油超深度加氢脱硫反应的影响。结果表明:采用催化剂级配时与单独使用Ni-Mo-W催化剂时的超深度加氢脱硫效果相当;在第一反应器采用Ni-Mo-W型催化剂、第二反应器采用Ni-W型催化剂时,可有效降低加氢柴油产品的密度与多环芳烃含量;在第一反应器采用Ni-Mo-W型与Co-Mo型催化剂等体积比级配、第二反应器采用Co-Mo型催化剂的级配方案时,可有效降低柴油加氢反应的氢耗。
In order to make better use of catalysts in different reaction regions of diesel ultra deep hydrodesulfurization technology (RTS),in which two reactors in series were adopted,grading schemes for Ni-Mo-W type catalyst with high hydrogenation activity, Co-Mo type catalyst with high direct desulfurization activity,and Ni-W type catalyst with slight hydro-upgrading activity were compared in the pilot plant.The results showed that the effect of graded catalysts system on ultra-deep hydrodesulfurization was comparable to that of Ni-Mo-W catalyst alone.If Ni-Mo-W type catalyst was used in the first reactor and Ni-W type catalyst in the second reactor,the density and polycyclic aromatic hydrocarbon content of the product was effectively reduced.If the first reactor used Ni-Mo-W type and Co-Mo type catalyst in equal volume,and Co-Mo type catalyst was used in the second reactor,the hydrogen consumption could be effectively reduced.
