Co/Al2O3-SiO2催化剂的F-T反应性能的研究
Study on the F-T reaction performance of Co/Al2O3-SiO2 catalyst
摘要
Abstract
The γ-Al2 O3 modified with different content of SiO2 by impregnation method was used as supports to prepare Co/Al2O3 catalyst.The effects of SiO2 additives on phase structure of the cobalt-based catalysts,reduction behavior and the influence on the F-T synthesis performance were studied by using N2 adsorption,XRD,H2-TPR and XPS characterization methods and activity test.The results showed that with the introduction of SiO2,the interaction between support and cobalt was effectively weakened,thus the reducibility and catalytic activity of the catalysts were significantly improved.However,when the amount of SiO2 continued to increase,the reduction degree of the catalyst continued to improve,but the dispersion decreased by 32％ at the same time.Compared with unmodified Co/Al2 O3 catalyst,the activity of the catalyst remained basically unchanged.关键词
