摘要：

The elimination of mercury vapours from gaseous streams has been studied using sulfurized silicates as adsorbents. A new method to sulfurize the materials based in hydrogen sulfide oxidation at low temperature is proposed. The sulfur produced in the reaction is deposited on the material, its dispersion depending on the process temperature and physico-chemical properties of the silicates used. The adsorbents were tested in static and dynamic systems for mercury depuration of gaseous streams. Commercial sulfurized active carbon was used as a reference. X-ray diffraction, atomic absorption spectroscopy, X-ray photoelectron spectroscopy, nitrogen adsorption-desorption and mercury intrusion porosimetry were used in raw materials and adsorbents characterization.
