Summary: | Based on new own and known published experimental data a microkinetic model of steam and dry methane reforming on Ni-catalyst is proposed and proved. The model eliminates drawbacks of the known previous models. The kinetic equations are derived.
A critical analysis of known kinetic models of methane reforming on Ni-catalyst is performed. Based on new own and known published experimental data a microkinetic model of steam and dry methane reforming on Ni-catalyst is proposed and proved. The model eliminates drawbacks of the known previous models. The kinetic equations are derived. Kinetic parameters of the model are adjusted by means of mathematical modeling with the use of own and published data. Pore-diffusion resistance was taken into account during calculations. The obtained values of kinetic parameters agree with the estimated ones obtained according to the transition state theory. |
