Abstract
This paper presents the results of performance tests of various kinds of adsorbents by static and dynamic adsorption methods to select the optimum deodrant (adsorbent) for ammonia gas (NH3).<BR>In the peformance test of the static adsorption method, the amounts of NH3 adsorbed by 21 kinds of adsorbents including physical and chemical adsorbents were measured.<BR>The amounts adsorbed physical adsorbent No.6, chemical adsorbents No.18, No.19 and No.20 which showed higher adsorption ability were 0.0160g/g, 0.0284g/g, 0.0250g/g, 0.0249g/g respectively at 30°C under equilibrium preasure of 50mmHg. All of the adsorbent showed in Freundlich's adsorption isotherm for NH3. Although the correlation between specific area, pore volume, mean pore radius, pH each adsorbent and the amount of adsorbed were tried, the correlation between the pH and the amount of NH3 adsorbed was significant. This suggests that the pH is a proper criterion for selection for adsorbents.<BR>The performance test of the dynamic adsorption method, was conducted for adsorbents No.6, 18, 19 and 20 above-mentined. The 10% breakthrough time was compared as the performance index. The breakthrough time of the adsorbent whith the amount adsorbed was large was long but the breakthrough time was not proportional to the amount adsorbed.<BR>These results suggest that the perfoemance test only by the static adsorption method is insufficient and that the breakthrough time test by the dynamic adsorption method is essential.
