摘要
显微计算机断层扫描技术(Micro-CT)是一种无损检测方法,可以快速准确地建立分析对象的3D结构和组成.以工业运转后的渣油加氢保护剂为研究对象,创造性地引入Micro-CT对渣油加氢保护剂的微观结构进行了 3D重构研究.通过比对Micro-CT切片数据离散图与扫描电镜元素离散图分布,对保护剂中孔隙、金属沉积物进行了识别与确认,并采用3D重构技术重建了孔隙及沉积物的三维分布模型.结果表明,利用Micro-CT可以从微米到纳米尺度构建保护剂的3D结构模型;发现工业运转后的渣油加氢保护剂内部还有大量未被使用的封闭孔,增加孔道的连通性是提高保护剂效率的关键.这种全新的渣油加氢保护剂微观结构分析方法能为渣油加氢保护剂的开发提供指导.
Abstract
Micro computed tomography(Micro-CT)is a non-destructive testing method that can quickly and accurately establish the 3D structure and composition of analytical objects.Taking the residue hydrotreating protectants after industrial operation as the research object,Micro-CT was introduced to characterize the microstructure of the residue hydrotreating protectant in 3D model creatively.By comparing the discrete graph of Micro-CT slice data with the distribution of SEM element discrete graph,the pores,metal sediments in the protectant were identified and confirmed,and 3D reconstruction technology was used to reconstruct the three-dimensional distribution model of pores and metal sediments.The results indicated that Micro-CT could construct 3D structures of protectant from micron to nano-scale.There were still a large number of unused closed pores inside the protectant,and increasing the connectivity of the pores was the key to improving the efficiency of the protectant.As a novel microstructural analysis method for residual oil hydrogenation protectant,Micro-CT can provide guidance for the development of residual oil hydrogenation protectant.
