Abstract
The present work reports the synthesis and application of sulfur doped into porous activated carbon for removing elemental mercury from natural gas using a bench-scale fixed-bed reactor. A series of experiments were carried out to investigate the optimization of Hg 0 capture. Furthermore, our experimental results about optimum conditions to remove Hg 0 were 1:10 of sulfur to activated carbon impregnation ratio, 350 ° C of impregnation temperature, and 3 hours of impregnation time. This research showed that the prepared adsorbents were capable to remove remarkable amount of Hg 0 (23.615 mg/g) at high adsorption efficiency. This study may serve as reference on natural gas power plants for the removal of Hg 0 using the same conditions.
