摘要

采用水滑石法制备了nixmg6 - xal1.8 - ce0.2(0≤x≤6)混合氧化物催化剂。所有氧化物在800℃下煅烧,用不同的物理化学方法对其进行了表征,并测试了它们对甲苯蒸汽重整的催化性能。在蒸汽重整过程中,还原预处理是催化剂活化的必要步骤。Ni2Mg4Al1.8Ce0.2表现出较好的甲苯转化率和最佳的产氢性能。

Steam reforming of toluene for hydrogen production over NiMgALCe catalysts prepared via hydrotalcite route
NixMg6-xAl1.8Ce0.2 (with 0 ≤ x ≤ 6) mixed oxides catalysts were prepared by hydrotalcite route. All the oxides were calcined at 800°C and characterized by different physicochemical methods and their catalytic performances were tested toward steam reforming of Toluene. In the steam reforming process, reducing pretreatment is a necessary step to activate the catalyst. Ni2Mg4Al1.8Ce0.2 shows the better toluene conversion and the best performance (H2 production) among all the catalysts.
