摘要
本文对不同配方及制备方法的NiO-MoO_3/γ-Al_2O_3型催化剂进行了磁性测定,讨论了各种情况下Ni ̄(2+)的存在状态,并与催化剂的低变活性相对照。证实了Ni ̄(2+)的存在位置与其本身的含量及MoO_3含量,浸Ni前是否焙烧,K_2CO_3的浸渍等均有关,且对活性有明显的影响。
In this paper , Nio-MoO_3/γ-Al_2O_3 water gas shift catalysts had been studied bymeans of magnetic measurements,It was found that the content of active components and the prepa-ration method have significantly influence on sites of Ni ̄(2+),simultaneously, the higher activity ofthe catalyst is closely related to the higher concentration of Ni ̄(2+) in octahedral sites.
