Characterization and kinetics of light crude oil combustion in the presence of metallic salts

In this research, a reaction cell, thermogravimetry (TG), and differential thermal analysis (DTA) were used to characterize the light crude oil combustion and kinetics in the presence of copper(I) chloride (CuCl) and magnesium chloride (MgCl2·6H2O). In TG-DTA experiments with magnesium chloride, three reaction regions were identified, known as distillation, low-temperature oxidation (LTO), and high-temperature oxidation (HTO). In the case of copper(I) chloride, two main transitional stages are observed with distillation and high-temperature oxidation (HTO). It was also observed that, as the mol % of magnesium chloride increased, the high-temperature oxidation peak shifted to the lower-temperature region reflecting more homogeneous composition of the solid residue. In the case of reaction cell experiments, it was observed that the molar CO2/CO ratio values of fuel combustion increased with the addition of metallic salts. A decrease in the atomic H/C ratio with an increase in temperature was observed in all experiments performed.
