The results indicated that a dependable kinetic model could be obtained by modifying the Temkin equation by considering the H2 and NH3 adsorption factors. Activation energy for the ammonia synthesis reaction was obtained as 90.2 kJmol^(-1) after linear fitting the kinetic and thermodynamic parameters k, K(subscript H2) and K(subscript NH3) with the Arrhenius and Van't Hoff equation, which was much lower than that over iron-based catalyst, which indicated that the activation energy barrier of N2 dissociative adsorption on Ru was far lower than that on either the conventional magnetite-based catalyst or wustite-based catalyst; the hydrogen adsorption heat was 76.2 kJ mol^(-1), indicating that the adsorption of hydrogen on the Ba-Ru-K/AC catalyst was so strong that it inhibitied the dissociative adsorption of nitrogen.
