Modeling of temperature-programmed surface reactions

Temperature-programmed surface reaction (TPSR) experiments with a ruthenium -based catalyst supported on MgO were conducted in a microreactor flow syst em. The hydrogenation of preadsorbed atomic nitrogen obtained under various experimental conditions has been studied followed by a detailed microkinet ic analysis including an evaluation of the influence of backmixing, The sha pe of the TPSR profile was found to depend strongly on the initial surface coverage and on the presence of coadsorbates.
