As part of a study to evaluate the performance of a “dry” catalytic method of removing low concentrations of H 2 S from cupola gas, the rate of oxidation of low concentrations of H 2 S by air at room temperature has been studied using a fixed activated carbon bed. Previous studies have presented somewhat contradictory results. It was found that the rate decreased with time, consistent with a rapidly fouling catalyst, and finally attained a steady state value. A mechanism is presented which is in agreement with the results. The oxidation rate was also found to increase drastically by increasing the air humidity, contrary to the published results of some other workers.
