Abstract

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.
