Popis: In this research, the catalytic effect of four types of clays on crude oil low-temperature oxidation was analyzed in depth via static oxidation tube experiments and DTG-DTA tests. Results show that the LTO reactions are positively brought to a deeper degree by clays through lowering the energy requirement for the oxidation/cracking reactions, accelerating reaction rates, and depositing more coke-like fuel. All samples exhibit endothermic oxidation behavior and their energy requirements are proportional to mass loss rates. Based on catalytic study on the oxidation and thermokinetic behaviors of crude oil, a high degree of consistency is discovered between the two types of thermal analysis methods.
