Abstract:研究了三种氧化铝载体和一种ZnO/theta-Al_2O_3催化剂对全馏分FCC汽油的选择性加氢脱硫性能. 结果表明,
   theta-Al_2O_3对于全馏分FCC汽油的加氢脱硫选择性因子高于gamma-Al_2O_3和在900
   ℃下焙烧过的gamma-Al_2O_3. 负载ZnO能进一步提高theta-Al_2O_3的加氢脱硫活性和选择性.
   通过吡啶吸附傅里叶变换红外光谱、氢气程序升温还原和X射线衍射表征发现,
   theta-Al_2O_3表面只有微弱的L酸性,其吡啶吸附红外光谱明显不同于其他氧化铝.
   负载ZnO导致theta-Al_2O_3载体中出现了尖晶石结构,并且使催化剂的高温H2还原峰位向低温方向移动.
