Especially designed experiments enabled determination of selectivity of individual gauzes of a catalytic pack in the process of oxidation of ammonia. It has been found that changes in selectivity observed along a pack comprising partially weared gauzes were opposite to those in a pack consisting of new gauzes. In both the cases, changes in selectivity were more dependent upon load of the catalytic bed than on initial temperature of the reagent gas. It seems obvious, that these very distinct differences in selectivity characteristics between new and weared gauzes are due to reconstruction of the near-surface layers of the catalyst, which proceeds during long-lasting operation. Therefore, it may be concluded that new gauze and used gauze are two qualitatively different catalysts.
