摘要
采用程序升温还原法(TPR)对CO与H2合成低碳烃催化剂Co-Fe-Cu/SiO2各组分之间相互作用进行了研究,结果表明钴与铁的混合使钴、铁氧化物的还原温度明显降低,少量铜的掺入使其还原温度进一步降低.正是由于Co,Fe。
Catalysts,such as CoO/SiO 2,Fe 2O 3/SiO 2,CoO-Fe 2O 3/SiO 2,CoO-Fe 2O 3-CuO/SiO 2,are investigated by using TPR.The results show that mixing of CoO and Fe 2O 3 make their reduction temperature decreased and addition of a small amount of copper to the binary mixture leads to a further decrease in reduction temperature.It suggests that the strong interaction among Co,Fe and Cu that make Co-Fe-Cu/SiO 2 have high activity and selectivity for the formation of LGP from Co and H 2.
