摘要

完成了Castilla和Jazmín哥伦比亚原油焦炭的非晶分类。这些重质原油在精炼阶段经过分馏后，进行物理化学表征，并进行焦化处理。根据芳香族碳的类型对原料的化学成分进行了表征，得出了上述结论。用紫外可见分光光度法和扫描电镜(SEM)在100 ~ 5000X的放大范围内对焦炭样品进行了分析。本工作的结果可以确定不同焦化原料的多芳香族化合物浓度比(四芳香族/三芳香族，二芳族/三芳香族)功能的形态分类间隔。此外，原料中高含量的钙和硫促进了伴生丸型的形态。

MORPHOLOGICAL CLASSIFICATION OF COKE FORMED FROM THE CASTILLA AND JAZMÍN CRUDE OILS

Amorphological classification of cokes from the Castilla and Jazmín Colombian crude oils was completed. These heavy-nature crude oils, after being fractioned during the refining stages, were physicochemically characterized and submitted to the coking process. The conclusions of this work are based on the characterization of the feedstock chemical composition according to the type of aromatic carbon. UV visible spectrophotometry and the corresponding micrographs obtained by a Scan Electron Microscope (SEM), in amplification intervals from 100X to 5000X for the samples of formed cokes, were analyzed. Results of this work allowed the determination of the morphological classification intervals in function of the polyaromatic compound concentration ratio (tetraromatic / triaromatic, and diaromatic / triaromatic) of the different coked feedstocks. Furthermore, high content of calcium and sulfur in the feedstocks promotes morphologies of the associated - shot type.
