Non-carbon sorbents for mercury removal from flue gases

TDA Research, Inc. is developing a new sorbent that can effectively remove mercury from flue gases. The sorbent achieved 1.1 mg/g mercury absorption capacity on a breakthrough basis under representative flue gas streams. The sorbent also showed resistance to sulfur poisoning by sulfur dioxide.

Graphical AbstractTDA Research is developing a new sorbent/catalyst to carry out oxidation of mercury and the capture and removal of mercury species. The sorbent is made of non-carbon based materials and has high mercury absorption capacity, thus will not alter the properties of the fly ash. The sorbent can be produced as injectable powder for integration into the existing power plant infrastructure.Figure optionsDownload full-size imageDownload as PowerPoint slide
