摘要： 采用溶胶-凝胶法制备过渡金属改性纳米TiO2催化剂并进行了表征，用于FCC汽油模型含硫化合物脱硫。考察了TiO2的用量、四丁基溴化铵的用量以及Fe、Ni、Cu、Zn掺杂量对脱硫效果的影响。结果表明，FCC汽油与甲酸体积比为1∶1、7.5%（mol）Ni-TiO2 20 mg、加入5 mg四丁基溴化铵、光照3 h条件下，脱硫率最高达到98.4%。

Abstract: Transition metal modified nano-titanium dioxide was prepared by the sol-gel method and characterized. Desulfurization of sulfur compounds in FCC naphtha with the prepared catalyst was investigated. The effects of TiO2 dosage，addition of tetrabutyl ammonium bromide, doping by Fe, Ni, Cu, Zn and reaction time on desulfurization performance were studied. Test results showed that under the conditions of using FCC naphtha，a volume ratio of naphtha to formic acid of 1∶1，7.5％（mol）Ni-TiO2 20mg，adding 5mg tetrabutyl ammonium bromide，illumination 3h，desulfurization rate was up to 98.4%.
