The kinetics of coke combustion at temperatures of 525–650°C on a K–CrOx/γ-Al2O3 catalyst for the direct dehydrogenation of n-butane to butadiene-1,3, which is an analogue of a commercial catalyst, has been studied. It has been shown that under the studied conditions, the coke combustion reaction is described by a first-order kinetic equation with respect oxygen and coke at an apparent activation energy of ~93 kJ/mol. The adequacy of the kinetic model has been confirmed by agreement between the calculated results and the test data.
