Laws of regeneration of catalyster of methane oxycondensation reaction

The mechanism and kinetics of coke-forming decontamination of the catalyst used in the catalytic oxycondensation reaction of methane were studied. Changes in the oxygen concentration at the outlet of the reactor over time at different temperatures were studied, and experimental data on the oxygen concentration were found to depend on the regeneration time. A mathematical model of an ideal extrusion reactor was used to describe the experimental dependences obtained at different initial concentrations of oxygen coke. Based on the calculated values of velocity constants at different temperatures, the activation energy of the coke combustion reaction was determined. Based on the obtained results, it was proved that the activation energy of the coke combustion reaction is 75.8 ± 5 kJ/mol, the activation energy of coke formation is 23.95 kJ/mol.
