本文使用GPU计算单元基于聚类分析数学方法处理高岭土、NaY分子筛以及负载晶化NaY分子筛的透射电镜(TEM)图像。将所提取的几类图像的灰度数据信息,分别进行归一化、相关矩阵计算及特征分解、特征值和特征向量的提取以及灰度值向量的二维投影等过程处理,进而对高岭土负载晶化NaY分子筛进行空间分辨分析,并对高岭土负载晶化NaY分子筛空间各类基质可能的富集区域进行标示和分析。同时,基于分辨分析的结果,对高岭土负载晶化NaY分子筛的空间组构及表面的吸附扩散行为进行讨论,该分辨方法对于石油炼制领域广泛使用的复合共生分子筛或其它复合催化材料体系的分辨也有较大意义。同时,也采用了单晶衍射、电子能谱分析、表面面扫描以及频率响应等辅助分析方法对空间分辨分析的结果进行进一步的支持和论证。
In this paper, transmission electron microscopy (TEM) images of kaolin, NaY zeolite and NaY zeolite loaded with crystallization were processed by GPU computing unit based on mathematical analysis of clustering analysis. The gray value data of the extracted images are normalized, the correlation matrix is calculated and the feature decomposition, the extraction of the eigenvalue and eigenvector and the two-dimensional projection of the gray value vector are processed, and then the kaolinite load Crystallized NaY zeolite for spatial resolution analysis and identification and analysis of possible enrichment regions for various types of matrix in kaolinite loaded NaY zeolite space. At the same time, based on the results of resolution analysis, the spatial structure and adsorption-diffusion behavior of kaolin-loaded NaY zeolite were discussed. The resolution method was applied to the resolution of widely used composite symbiosis molecular sieves or other composite catalytic materials in petroleum refining Also of great significance. At the same time, we also use the single-crystal diffraction, electron spectroscopy, surface scanning and frequency response analysis methods such as auxiliary analysis of spatial resolution results for further support and feasibility studies.
