Abstract
The kinetics of methane reforming over Ru/γ-Al 2O 3-catalyzed high porosity Ni–Cr–Al foam were examined at temperatures of 650–900 °C in a quartz tubular reactor using an electric furnace. The kinetic data were analyzed by four different types of kinetic models based on the basic, Eley–Rideal, Langmuir–Hinshelwood, and stepwise mechanisms. Validation of the kinetic models was carried out by calculating the determination coefficient r 2 between the predicted and the experimental results for each model. The absolute average deviation percentage (AAD%) between the predicted and the experimental results was also estimated for each model. The kinetic model based on the reversible stepwise mechanism provided the best prediction of the experimental reforming rates with an AAD value of 6% in the range 650–850 °C.
