To intensify the catalytic process of methane dry reforming with carbon dioxide, i.e. to enhance the syngas formation activity and catalyst stability, kinetic analysis of the reaction over Ni/Al(2)O(3) catalysts at 873 K was perfomed. The rate equation was derived based on Langmuir-Hinshelwood type kinetics. The reaction orders for CH(4), CO(2), H(2), and CO were evaluated to be 1, -0.5, 0, and -1, respectively. It should be noted that the negative orders were obtained for the pressure dependence of CO(2) and CO. These results strongly suggest that the surface of the catalysts, Ni surface, was significantly covered by CO and CO(2) ( or O species produced from dissociation of CO(2) together with CO). The rate equation derived here is expected to be a powerful tool for the process intensification of the reaction, because it allows prediction of not only the total reaction rate but also the variation of surface adsorption states.
