Sorbents for removal of Lead compounds from hot flue gases

Control of Toxic Metal Emissions from Combustors Using Sorbents: A Review

“…25,64,66,[138][139][140][141][142][143][144][145][146][147][148][149] Shadman and et al 139,[150][151][152] have demonstrated the effectiveness of sorbents (alumina, bauxite, emathlite, kaolinite, silica, limestone) for the capture of lead, cadmium, and other alkali metal vapors. Wu et al 181 extended their earlier studies to the development of a multifunctional sorbent for capture of sulfur dioxide, alkali metals, and lead.…”

Control of Trace Metal Emissions During Coal Combustion

“…Chemical absorption reactions between metal vapors and a variety of sorbents at high temperatures have been observed both in a packed bed and in a fluidized bed (see, e.g., Punjak et al, 1989;Uberol and Shadman, 1990;Ho et al, 1992Ho et al, , 1994. The following reactions between metals and sorbent constituents have been confirmed both theoretically and experimentally:…”
