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 Hg0 capture. Furthermore, our experimental results about optimum conditions to remove Hg0 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 Hg0 (23.615 mg/g) at high adsorption efficiency. This study may serve as reference on natural gas power plants for the removal of Hg0 using the same conditions.

Recent study have showed that the highly adsorptive porous carbon can be prepared by high temperature sulfur impregnation, authors performed a series of experiments for removing mercury from natural gas by employing elemental sulfur doped coconut husk porous activated carbon, this study has found that factors such as the impregnation temperature and impregnation ratio were the most important factors played a critical role for the hole process of mercury re
The main objective of this research was to optimize Sulfur doped into Porous Activated Carbon adsorbent preparation focusing on the art of the impregnation technique with high-temperature between 300 ̊C - 500 ̊C for natural gas to remove the Hg0 using bench-scale fixed bed reactor
Summary
Natural gas is one of the three major fossil fuels sources of energy including petroleum, and coal. Natural gas is a versatile, clean-burning, and efficient fuel accounted for most of the energy production [1]. Mercury is recognized as a toxic metal, its presence has been a serious concern to natural gas processing plants [2] [3] [4] [5]. Mercury is among the current top environmental challenges due to a rapid industrial growth. The exposure to mercury may leads to receive global emphasis through its continuing and serious harm to human health effects ranging from acute to chronic diseases [2]
