A review on coal fly ash-based adsorbents for mercury and

10/09/2020· From the studies reviewed, it is found that the raw fly ash sorbents achieve mercury removal efficiencies of 11–66%, while for modified fly ash achieve 44–100% efficiencies. The addition of HBr, CuBr 2, Mn, and Fe shows the highest enhancement effect. Further improvements can be made through optimizing sorbent preparation parameters and adsorption conditions. The capture efficiency

Sorbents for mercury removal from flue gas (Technical

ADA Technologies, Inc. (Englewood, Colorado), in conjunction with the US DOE, is developing regenerable sorbents for the removal and recovery of mercury from flue gas. These sorbents are based on the ability of noble metals to amalgamate mercury at typical flue-gas temperatures and release mercury at higher temperatures. The process allows for recovery of mercury

Sorbents for Mercury Capture from Fuel Gas with

In regard to gasification for power generation, the removal of mercury by sorbents at elevated temperatures preserves the higher thermal efficiency of the integrated gasification combined cycle system. Unfortunately, most sorbents display poor capacity for elemental mercury at elevated temperatures. Previous experience with sorbents in flue gas has allowed for judicious selection of

Cost-Effective Manganese Ore Sorbent for Elemental

Natural manganese ore (NMO) was developed as a cost-effective sorbent for elemental mercury removal from flue gas. NMO sorbent showed excellent Hg0 removal efficiency (>90%) in a wide temperature window (100–250 °C) under the conditions of simulated flue gas. O2, NO, and HCl promoted Hg0 removal due to the surface reactions of Hg0 with these species. SO2 and H2O slightly inhibited

Analysis of solid sorbents for control and removal

Due to the restriction such as the Minamata Convention as well as the IED of the European Commission, mercury removal from flue gases of coal-fired power plants (CPP) is an increasingly important environmental issue. This makes this topic very crucial for both the energy industry and scientists. This paper shows how mercury arises from natural resources, i.e., coals, through their combustion
