对Ni/Al_2O_3催化剂体系的制备方法与其结构和性能的关系已有不少研究报道,文献多侧重于比较各不同制备方法之间的差异,对同一方法的各步骤条件的影响研究尚不多,且缺少微观结构与宏观性能的直接关联。为此,本文研究了某些制备因素对低含Ni量Ni/Al_2O_3催化剂性能的影响,旨在找出制备条件-结构状态-催化性能之间的联系,为催化剂的有效设计提供依据。
There have been many reports on the relationship between the preparation methods of Ni / Al_2O_3 catalyst system and its structure and properties. The literature focuses on comparing the differences between the different preparation methods. However, there is not much research on the influence of each step conditions on the same method, And lack of a direct correlation between microstructure and macro performance. For this reason, the influence of some preparation factors on the performance of Ni / Al_2O_3 catalyst with low Ni content was studied in this paper. The aim was to find out the relationship between the preparation conditions, structure state and catalytic performance, and provide the basis for the effective catalyst design.
