Removal and recovery of gas-phase element mercury by metal oxide-loaded activated carbon

Simultaneous Control of Elemental Mercury/Sulfur Dioxide/Nitrogen Monoxide from Coal-Fired Flue Gases with Metal Oxide-Impregnated Activated Carbon

“…Mei et al (2008) indicated that high loading values and adsorption temperatures increased the Hg 0 removal percentage by Co 3 O 4 -doped activated carbon; the CuCoO 4 -doped activated carbon also showed the greatest SO 2 removal efficiency. Tian et al (2009) demonstrated that the doped CeO 2 in activated carbon significantly promoted the adsorption ability for Hg 0 .…”

Removal of elemental mercury from flue gas by recyclable CuCl 2 modified magnetospheres catalyst from fly ash. Part 1. Catalyst characterization and performance evaluation

“…In contrast, the excess loading value would decrease the dispersion degree of CuCl 2 on the catalyst surface as well as the surface area. This might prevent the valid collision between Hg 0 and active oxidation sites on the catalyst [40], thus decreased the Hg 0 adsorption capacity.…”

Overlook of carbonaceous adsorbents and processing methods for elemental mercury removal

“…Especially, porous materials (including activated carbons, zeolites, and alumina powders) are useful materials for gas adsorption and storage [42][43][44][45][46][47][48][49]. Adsorption, especially using activated carbon (AC) as adsorbent, is currently the most widely used technology for hazardous gas removal from the incineration flue gases [50][51][52][53][54][55][56][57][58][59][60][61]. As for the sorbent injection technique, activated carbons are injected into the flue gas right before it enters the electrostatic precipitators or bag house filters.…”
