耐硫变换催化剂中活性组分钴、钼的相互作用

INTERACTION BETWEEN Co and Mo ACTIVE COMPONENTS OF SULFUR-TOLERANT CO CONVERSION CATAlYST

采用常压微反评价、程序升温还原 (TPR)和硫化 (TPS)技术及原位红外 (IR)技术 ,对不同活性组分的CoO MgO Al2 O3 TiO2 、MoO3 MgO Al2 O3 TiO2 和CoO MoO3 MgO Al2 O3 TiO2 的变换活性及性能进行了表征测试 ,结果表明 :单独的硫化钴或硫化钼都具有耐硫变换活性 ,单独硫化钴作为活性组分的催化剂活性优于单独硫化钼作为活性组分的催化剂 ,并且二者之间具有明显的协同效应。

The CO conversion activities and other performances of CoO/MgO Al 2O 3 TiO 2, MoO 3/MgO Al 2O 3 TiO 2 and CoO MoO 3/MgO Al 2O 3 TiO 2 samples have been characterized by using of GC Microreactor, Temperature Programmed Reduction (TPR), Temperature Programmed Sulfurization (TPS) and in situ infra red spectroscopy The results show that only cobalt sulfide or molybdenum sulfide itself has CO conversion activity, and the activity of sole cobalt sulfide catalyst sample is higher than that of sole molybdenum sulfide sample Furthermore, there is a distinct co efficiency between the two sulfide active components
