摘要：

Bimetallic Pt-Sn/Al2O3 catalysts were prepared by the sol-gel method by adding Sn(But)4 to a homogeneous solution containing aluminum tri-sec-butoxide at pH = 9. After gelation, the solids were dried and impregnated with hexachloroplatinic acid solution. The resulting catalysts were highly dispersed (90%) and selective to gasoline yields when tested in n-heptane dehydrocyclization.
