摘　　要：结合分子筛ZSM-5与SBA-15自身的优点,合成了不同质量比例的ZSM-5/SBA-15微孔-介孔复合分子筛,并进行XRD、N2吸附-脱附表征,分析其结构特征。以其为载体负载金属W、Ni、Ce、Cu,制备出不同的氧化脱硫催化剂,对模拟油进行氧化脱硫研究。结果表明,负载金属W制备出的WO3-ZSM-5/SBA-15(ZSM-5质量分数为10%)复合分子筛,脱硫效果最好,脱硫率为75.44%。Combined with the advantages of ZSM-5 and SBA-15 sieve moleculars respectively,different mass ratio of ZSM-5 / SBA-15 micro-mesopore composite molecular sieves were synthesized and characterized by XRD,N2 adsorption and desorption. Different oxidative desulfurization catalysts were prepared by loading metal W,Ni,Ce and Cu on ZSM-5 / SBA-15 and applied to model oil system. The results showed that the desulfurization rate could reach to 75. 44% by using WO3-ZSM-5 / SBA-15 as catalyst with the mass ratio of ZSM-5 of 10%.
