title = "REMOVAL OF THE CORROSIVE HYDROGEN SULFIDE POLLUTANT FROM THE INTAKE AIR FOR A CONTROLLED ENVIRONMENT.",
abstract = "The contact point corrosion of the telephone switching equipment in a spa area was investigated. It has been found that the observed corrosion is mainly due to the high H//2S concentration ( less than 90 ppb) in the local atmosphere. Since the switching office is in an air conditioned enclosure, removal of H//2S from the intake air was considered as an effective method to eliminate such corrosion. An adsorbent made of zinc oxide and clay was selected for removal of H//2S. Cylindrical pellets of this adsorbent were prepared by extrusion of the mixed-mud, and then by 800 degree C calcination. The adsorption capacity and kinetics of trace H//2S in a constant volume system were studied and analyzed with a shrinking core model. The SEM-EDS analysis on the cross sections of the pellets confirms the layer progression of the reacted front. It was found that the adsorption capacity is 2. 74 mg/g and the effective diffusivity of the pores is 0. 03 cm**2/sec.",
