Thermodynamic equilibrium analyses of transformation and partition of Pb during sludge incineration

The chemical thermodynamic equilibrium analyses were used to explore the migration and transformation of Pb during sludge incineration, and the influences of S, Cl and adsorbents were also studied. The result show that the main form of Pb is PbO(g) and PbCl(g) at 1000K due to its highly volatile. Ch...

Description
Summary:The chemical thermodynamic equilibrium analyses were used to explore the migration and transformation of Pb during sludge incineration, and the influences of S, Cl and adsorbents were also studied. The result show that the main form of Pb is PbO(g) and PbCl(g) at 1000K due to its highly volatile. Chlorine will promote the volatilization of Pb, reduce the initial volatile temperature, and increase volatilizing rate, while the effect of sulfur is not obvious. Al2O3 and SiO2 can all form solid state compound with Pb, thus inhibiting its volatilization.
