摘要：
The effect of the diffusion of oxygen from the volume of the catalyst to its surface on the dynamics of the oxidative coupling of methane was assessed on the basis of a mathematical model of the reaction of methane with the oxidized surface of KNaSrCoO3–x perovskite. It was shown that the possible values of the diffusion coefficient lie in the range of 10-18-10-16 cm2/s characteristic of the diffusion of oxygen in oxide catalysts.
