An investigation of the chemical form, the concentration, and distribution of lead species between the gas and condensed phase was carried out under gasification-like conditions. The influence of hydrogen sulfide, hydrogen chloride, and steam on the speciation of lead was studied. The gaseous species were determined online by molecular-beam-mass spectrometry. The condensates were analyzed by standard methods. The dominant chemical forms were metallic Pb, PbCl2, and PbS. The experimental data were compared with the results of thermodynamic Scheil-Gulliver cooling calculations. Further, the experimental data was used as an input for a pseudoequilibrium model aiming at the determination of kinetic information on the underlying transformations.
