چکیده:

The kinetic behavior of the Ni/La2O3, Rh/La2O3 and LaNiO3 catalysts in the reforming reaction of methane with carbon dioxide was investigated as a function of temperature and partial pressures of CH4 and CO2. The coefficients of the rate equation were estimated for three catalysts by genetic algorithm. It was shown that Rh/La2O3 and LaNiO3 (in the high temperature) catalysts have higher activity in comparison with Ni/La2O3. So at the temperature above 700°C, LaNiO3 ( perovskite) shows higher activity than Ni/La2O3 in dry reforming.
