Abstract
The study of the oxidation of propane-ethylene mixtures by numerical kinetic modeling allowed us to establish that in the range of 400–600°C with an increase in the conversion of propane with an increase in temperature, the selectivity of propylene formation passes through a maximum whose position depends on the concentration of ethylene in the initial mixture. The addition of ethylene to the initial mixture leads to a reduction in propane consumption and an increase in the selectivity of propylene formation. The conditions under which ethylene introduced into the initial mixture is not consumed during the process are determined; thus, formally it can be considered as a catalyst, and the process of propane oxidation as proceeding in a pseudo-catalytic regime.
