Study of the Radical Chain Mechanism of Hydrocarbon Oxidation for In Situ Combustion Process

Abstract: Despite the abundance of in situ combustion models of oil oxidation, many of the effects are still beyond consideration. For example, until now, initial stages of oxidation were not considered from a position of radical chain process. This is a serious difficulty for the simulation of oil recovery process that involves air injection. To investigate the initial stages of oxidation, the paper considers the sequence of chemical reactions, including intermediate short-living compounds and radicals. We have attempt… Show more

“…Thermolysis of hydroperoxides generated primarily alkoxyl radical through homolytic cleavage (Equation 1), followed by second-generation carbon-centered radical formed through hydrogen abstraction by hydroxyl or alkoxyl radical (Equation 2). It is unlikely that carbon-centered radicals originated from direct pyrolysis of alkanes at 90 °C since liquid hydrocarbons are resistant to dissociation of the carbon-carbon bonds up to 200 °C [29].…”

“…In this case, the Eq. ( 8 ) provides a possibility to identify the occurrence of these two side reactions 15 . where K eff is the rate constant of antioxidant consumption in side reaction(s) of chain initiation and dependeds on the character of lipid substrate, W i (M s −1 ) is the average rate of initiation during IP, and f is the stoichiometric coefficient of inhibition, determining the number of peroxide radicals scavenged by an antioxidant molecule.…”

“…One-mm layers of the prepared oils (4 g) were oxidized in a Petri dish having a diameter of 9 cm. Under these conditions, the process took place in a kinetic regime, i.e., at a sufficiently high oxygen concentration which the diffusion rate does not influence the oxidation rate 15 . Three replications of the samples were stored.…”
