Kinetic laws and mechanisms of methane oxycondensation reaction

The study studied the kinetic laws and mechanism of the catalytic oxycondensation reaction of methane. Manganese-based oxide catalysts prepared by the absorption method for the oxycondensation reaction of methane have high catalytic activity and efficiency, and the best results were obtained in the presence of the catalyst (Mn₂O₃)_x (Na₂MoO₄)_y(ZrO₂)_z. The conversion of this catalyst methane was 52.6%, the selectivity for ethylene was 81.4%, and the yield of ethylene was 42.8%. The heterogeneous-homogeneous mechanism of the catalytic oxycondensation reaction of methane showed that the methane molecule interacts with the atomic oxygen in the catalyst defect to form the methyl radical CH₃ Methyl radicals CH₃ recombine in the gas phase to form C₂H₆. The resulting C₂H₆ crystal forms ethylene in the presence of oxygen atoms in the lattice defect.
