The kinetic models of oxidative coupling of methane catalyzed by perovskite were studied in a fixed bed flow reactor.
At atmospheric pressure, the reactions were carried out at 725-775◦C, inlet methane to oxygen ratios of 2 to 4.5 and
GHSV of 100 min-1.
Correlations of the kinetic data have been performed with the proposed mechanisms. The selected equations have been
regressed with experimental data accompanied by genetic algorithm in order to obtain optimized parameters. After
investigation the Langmuir-Hinshelwood mechanism was selected as the best mechanism and Arrhenius and adsorption
parameters of this model have been obtained by linear regression. In this research the Marquardt algorithm has also
been used for optimization and its results were compared with genetic algorithm.
