| 摘 要： | 采用高分辨率透射电镜-数字图像分析技术HRTEM-DI研究了焦炭微晶结构。焦炭微晶结构参数中的长度、曲率和倾角,可分别用来表达焦炭微晶大小、微晶片层的有序度和微晶堆砌有序度。提出的表征焦炭微晶大小和有序度的结晶指数,能够很好地反映焦炭微晶结晶程度对反应性的影响。

| Abstract: | The coke microcrystalline texture was studied by a high resolution transmission electron microscopy combined with digital image analytical technique (HRTEM-DI). The length, inclination angle and curvature characterization parameters of coke microcrystalline texture may be used to express the size of coke microcrystal, the order degree of microcrystalline lamellar and the order degree of microcrystalline stacking. The developed crystallographic index which is used to characterize the size and order degree could better reflect the effect of coke crystallinity on the coke reactivity. |
