摘要
A potential method of control of toxic metallic emissions is the use of sorbents for physical and chemical capture of toxic metal species. Equilibrium calculations have been used to determine the feasibility of using sorbents and to identify optimal operating regimes for maximum removal of metallic species. Three different sorbents are analyzed for capture of seven toxic metallic species encountered in coal combustion and waste incineration. The results of the simulation are compared to the limited available data reported in the literature. The speciation of metallic species is determined for typical coal combustion conditions and a parametric evaluation of metal-sorbent reactions is carried out. The role of chlorine content on the capture efficiencies is established.
