Effect of Adsorbed Nitrogen on Catalytic Activity of Ortho-Parahydrogen Conversion Catalysts
Knowledge of the influence of adsorbed impurities upon catalyst effectiveness is of theoretical and practical interest. The ortho-parahydrogen conversion mechanism in heterogeneous catalysis involves the adsorption of hydrogen. Any adsorbate which competes with hydrogen may be expected to reduce the catalyst effectiveness unless this competing adsorbate is also a catalyst. The extent and character of the reduction due to adsorption of an impurity may illuminate the catalyst behavior. Understanding of the effect of an impurity upon catalyst performance permits operating limitations to be placed upon the concentration of impurities in the feed stream to a liquefaction plant .
