Co/Mo/γ-Al_2O_3硫化物是重要的加氢精制、耐硫变换和耐硫甲烷化等反应用催化剂,因为此类催化剂中钴和钼的负载量较小(5～10wt%),且存在状态复杂,给催化剂表征带来困难.随着磁性测量技术的进步,磁性分析方法已成为催化剂表征的有力手段.钴作为一种具有特殊磁性的元素,在不同晶型或不同的化学环境中表现出不同的磁性,为用磁性分析方法研究Co/Mo/r-Al_2O_3催化剂的结构提供了便利条件.
Co / Mo / γ-Al_2O_3 sulfides are important catalysts for hydrotreating, sulfur-tolerant shift and methanation resistance because of the small loadings (5-10 wt%) of cobalt and molybdenum in such catalysts and The existence of complex state, difficult to catalyst characterization.With the progress of magnetic measurement technology, magnetic analysis has become a powerful catalyst for the characterization of the catalyst as a cobalt with special magnetic elements in different crystalline or different chemical environments Showed different magnetic properties, which provided a convenient condition for the study of the structure of Co / Mo / r-Al 2 O 3 catalyst by magnetic analysis.
