Coal-derived flue gas is one of the main anthropogenic sources of mercury emission. It is always desirable to remove mercury from flue gas to eliminate associated environmental problems, which would become more beneficial if mercury is removed and recovered as a useful material. In this research, the capture and recovery of Hg0 over the TMDC MoS2-based material were carried out to study the possibility of recovery of Hg0 as a resource. The capture of Hg0 achieved above 90% in the 180 min test at 50°C at a GHSV of 4.5×104 ml/(h·g). The recovery of Hg0 was conducted during the regeneration of the adsorbent. Three regeneration temperatures, i.e., 200, 250 to 300°C, were investigated. It was found that 200°C was the most appropriate operating temperature for the regeneration of the adsorbent, at which the maximum efficiency for the recovery of Hg0 was achieved. It can therefore be concluded that the TMDC MoS2-based material could be applied for the capture of Hg0 from flue gas as well as the recovery of Hg0 as a saleable product.
