在固定床实验装置上,分别考察了不同族单金属氧化物和MoO_3的二元复合氧化物吸附剂对FCC汽油中含硫化合物的脱除能力,用浸渍法改性自制的吸附剂,研究不同金属离子的改性效果;对不同Ni负载量的MoO_3作了X-射线衍射和比表面积分析.结果表明:MoO_3脱硫后硫质量分数为172.2 μg/g,CuO-MoO_3能使脱硫后硫质量分数减少至120.3 μg/g,用Ni改性MoO_3效果最好,最佳金属负载量约为3%,脱硫后硫质量分数达到50.6 μg/g.

The properties of monometal oxides in different groups and binary composite oxide adsorbents of MoO_3 for removing sulfur in FCC gasoline were investigated in a fixed-bed pilot plant. The self-made adsorbent was modified by impregnation and the influence of different metal ions on the same adsorbent matrix was researched. X-ray diffraction and specific surface area analysis for the different amount of Ni loading on MoO_3 were conducted. The results show that the desulfurization effect of MoO_3 achieves 172.2 μg/g. CuO-MoO_3 can reduce sulfur mass fraction to 120.3 μg/g. Taking MoO_3 for example, the most effective modifying metal is Ni and the proper content of Ni on molybdenum is about 3%. The sulfur mass fraction after desulfurization is 50.6 μg/g.
