本文介绍了选择衍射峰重心为变换原点、外延变换系数Fr(t)尾部和平滑分布函数等数据处理方法,消除了级数尾部效应等对分布函数的干扰,从而成功地测定了天然气转化催化剂活性组分Ni(111)的晶粒分布。显示了烧结型催化剂Ni(111)分布函数的双峰特征及其与活性等物化参数的关系。
In this paper, we introduce the data processing methods such as selecting the center of diffraction peak as the origin of transformation, tailing of Fr (t) and smoothed distribution function, and eliminating the interference of the tail function such as tail function to the distribution function, thus successfully measuring the activity of natural gas reforming catalyst Grain size distribution of Ni (111). The bimodal distribution of the Ni (111) distribution function and the relationship between the bimodal distribution and the physico-chemical parameters of the sintered catalyst are shown.
