In this research two Turkish crude oils (medium and heavy) wereseparated into their saturate,aromatic, resin, and asphaltene (SARA) fractions by columnchromatographic techniques, andcombustion experiments were carried out on whole crude oils and theirfractions by thermogravimentric analysis (TD/DTG) under air atmosphere at a 10 
C/minheating rate. Investigationof SARA fractions allows quantitative determination of the temperatureintervals at whichevaporation, oxidation, and combustion effects operate for eachfraction. In the course of thisresearch, the kinetic parameters of SARA fractions were determinedaccording to the Coats andRedfern technique. By using the data and findings of thisresearch, one can take advantage ofstudying the kinetics of SARA fractions instead of those of the complexwhole oil for modeling ofthe overall process to accurately predict combustion.
