Abstract
In this work the influence of catalysts on in situ combustion process of heavy crude oil has been studied. The heavy crude oil from Russia (Ashal'cha field) oil field was used. The research on oxidation was performed using accelerating rate calorimetry (ARC). The effect of type of metal oxide (NiO, Co3O4, Fe3O4) on catalytic oxidation process of crude oil at conditions close to reservoir's pressure and temperature was investigated. The impact of catalyst particle size on oxidation process of crude oil has been revealed. The composition of gas mixture has been shown to alter the activity of the catalyst in oxidation process. The correlation between type of catalyst as well as the composition of gas phase and kinetic parameters of reaction was found. Arrhenius kinetic parameters were derived from experimental data of crude oil oxidation.
