Abstract
A kinetic analysis of the model of oxidative conversion of methane to useful products based on a set of many possible elementary reactions that could most fully reflect the chemistry of the process and for which data on rate constants are available. The analysis was carried out numerically. Key stages of the mechanism were identified and used to predict conditions under which the process can be effectively carried out in order to obtain a mixture of methanol and formaldehyde or mainly methanol. It has been shown that high efficiency can be achieved at increased pressures of the reactive mixture due to the high methane content. The directionality of the process increases with decreasing temperature.
