The study of three capture agents with high efficiency for hydrogen sulfide

摘要

A rapid removal method of hydrogen sulfide (H_2S) gas is studied in the present paper at ambient conditions. These capture agents are powers of grain sizes and convenient for injection on H_2S gas at the site of accident. The agents are characterized by SEM and N_2 adsorption-desorption method, etc. The test on capturing H_2S was experimented and the result indicated that the prepared agents can reduce the H_2S concentration in the air to a harmless level rapidly.
