Abstract
Activated carbon is utilized as one of the most popular odor control measures. In designing an activated carbon bed, adsorption capacity and removal rate are very important factors. These factors are influenced by temperature and humidity.
The effects of temperature and humidity on hydrogen sulfide removal were therefore investigated in laboratory experiments. Removal of hydrogen sulfide by activated carbon involves not only physical adsoprtion but also oxidation. A higher temperature decreases adsorption capacity, but it increases the oxidation rate of hydrogen sulfide. Humidity in flow gas increases removal capacity. The removal rate depends on the concentration of hydrogen sulfide. It is believed that odor removal with an activated carbon bed can be performed more effectively based on information about thesefactors.
