- Abstract
- Kinetic parameters for methane pyrolysis on a NiO-CuO-AlO catalyst were obtained using mathematical modeling methods. The pre-exponential factor and activation energy were determined for two kinetic models, with the calculated values adequately describing the experimental points. The mathematical model was verified. Using a system of equations that takes into account catalyst deactivation over time and numerical calculations, the kinetic parameters of the deactivation process were determined: activation energy = 95 kJ/mol and values for different deactivation order . It was shown that in mathematical modeling of the catalytic pyrolysis of methane on a NiO-CuO-AlO catalyst, the root-mean-square relative error values do not exceed 2.5–7.9% in the high-temperature range of 625–650°C, which makes it possible to use both kinetic models for numerical calculations.
