文摘
The kinetics of the CO2 reforming of methane was investigated on a Ni-Rh-Al2O3 catalyst. Twenty-sevenmechanistic models were considered and fitted to the experimental data by numerically integrating the rateequation of the dry reforming of methane reaction. A thermodynamic analysis showed that the reverse watergas shift reaction operates in or very close to thermodynamic equilibrium. A strategy of model discriminationand parameter estimation led to a model that considers CO2 molecular adsorption, CH4 dissociative adsorption,and its surface chemical reaction as the rate-determining step. The parameter estimates in the resulting modelare statistically significant and thermodynamically consistent.
