AbstractThe sulfur capacity of metallurgical dusts from blast furnace ironmaking processes was measured in the temperature range from 298 to 923 K. The experimental results show that the sulfur capacity of metallurgical dusts is considerably increased with the increase of temperature from 298 to 923 K. The desulfurization ability of metallurgical dusts is mainly depend on its content of oxides of ZnO, PbO, CaO and MnO when the temperature is lower than 623 K, but when the temperature is higher than 623 K the contributions of iron oxides become dominant. Carbon content, due to its absorption effect, has a positive effect on the desulfurization ability of metallurgical dusts below 623 K. If the temperature increased to higher than 623 K the absorption effect of carbon disappears and the role of desulfurization reaction between H,S and the metal oxide such as ZnO, PbO, Fe2O3, CaO and MnO as well as the H2S diffusion in intraparticle of metallurgical dusts seems more important.; The sulfur capacity of metallurgical dusts from blast furnace ironmaking processes was measured in the temperature range from 298 to 923 K.
