摘要
使用色谱微反、TPS和原位IR等实验手段对Co/Al2 O3-MgO、Mo/Al2 O3-MgO和Co -Mo/Al2 O3-MgO进行了研究。结果表明 :Co、Mo在Al2 O3-MgO载体上都能处于高分散状态 ,处于高分散状态的Co、Mo容易发生协同作用 。
A series of Co, Mo and Co-Mo sulfur tolerant catalysts were studied using chromatographic microreactor, temperature-programmed sulfiding (TPS) technique and in-situ infra-red spectrum (IR). The results indicated that cobalt and molybdenum on Al2O3-MgO carrier were in high dispersion. The highly dispersed cobalt and molybdenum tend to function coordinately, thus promote shift activity of the catalyst.
