摘要/Abstract

摘要： 在传统催化汽油加氢脱硫催化剂基础上，以γ-Al₂O₃为载体，Co-Mo-Ni为活性组元，采用等体积浸渍方法制备了一种催化汽油深度加氢脱硫催化剂。研究了现有技术生产国Ⅴ汽油存在的问题，考察了载体、活性组元、金属负载量对催化剂催化性能的影响，并对催化剂稳定性进行了研究。结果表明：该催化剂对硫含量满足国Ⅳ标准（S≤50μg/g）的催化汽油产品进一步接力脱硫时，可脱除硫醇硫及其他形态硫，烯烃基本不饱和，加氢脱硫选择性高达90%以上。该催化剂作为国Ⅳ升级到国Ⅴ标准的重要技术，降低了现有国Ⅴ技术的辛烷值损失，技术经济性更好。

Abstract: A novel FCC deep hydrodesulfurization catalyst,composed of Al₂O₃ carrier and Co-Mo-Ni trimetallic active component,was synthesized by an incipient wetness impregnation method.The effects of carrier raw materials,active metal and metal loading on the catalyst activity and selectivity were studied as well as the stability of the catalyst.The experimental results showed that this catalyst had a high HDS selectivity (≥ 90%) for catalytic gasoline desulfurization products of national Ⅳ standard (S ≤ 50μg/g),and a high efficiency for the removal of mercaptan as well as other sulfur compounds,and was of little olefin saturation.The catalyst could be used as complementary technology for the production of ultra-low sulfur gasoline,which suffered a high RON loss,thus improved the techno-economics.

Key words: catalytic cracking gasoline, catalysis, hydrodesulfurization (HDS), selectivity, catalyst
