| 摘 要： | 采用TPR、XRD、XPS和H2脉冲吸附等表征手段考察了ZrO2助剂对Co/SiO2催化剂在Fischer-Tropsch(F-T)合成中稳定性的影响。结果表明，ZrO2的引入促进了钴物种在催化剂上的分散并明显抑制了该催化剂的失活；在反应过程中ZrO2起到结构助剂的作用，明显抑制了Co/SiO2催化剂上硅酸钴或水合硅酸钴物种的生成。

| Abstract: | TPR, XRD, XPS and H2-pulse adsorption were used to investigate the influence of zirconia on the stability of Co/SiO2 catalyst for Fischer-Tropsch synthesis. The results showed that the Co dispersion and the stability of the catalyst were both improved obviously as ZrO2 was introduced. Zirconia acted as a structural promoter and restrained the formation of the cobalt silicate and/or hydrosilicate species during the reaction. |
