Descripción : Thermal analysis of SARA fractions from atmospheric residue of heavy crude oil (12°API) was carried out to understand the way in which each fraction decompose to form coke. It was observed that asphaltenes are very prone to form coke as determined by thermogravimetric analysis (TG/DTG). Amount of coke for each component was saturates (0.3 wt%), aromatics (4.2 wt%), resins (4.6 wt%), asphaltenes (41.3 wt%), atmospheric residue (37.3 wt%). Activation energy (EA) was also calculated for aromatics, resins, asphaltenes, and atmospheric residue by using an isoconversional method based on Friedman’s procedure.
