Abstract: The aim of this work was to assess the influence of H2O, HCl, and H2S on the condensation and release of zinc. The condensation behavior of the zinc vapors was investigated in a heated flow channel reactor housed in a furnace with a gas cooling zone, where eight glass filters were placed on different cooling stages. The metal species deposited in the filters were determined by means of ion chromatography (IC) and inductively coupled plasma optical emission spectroscopy (ICP-OES). Experiments on the release of the inorganic vapors were carried out in a heated flow channel reactor coupled to a molecular beam mass spectrometer (MBMS). The experiments were carried out under two typical gasification conditions (H2/H2O/He or Ar) and atmospheric pressure with 50 and 500 ppmv of HCl and H2S. Hot gas analysis was done at 900, 800, 700, and 500 °C. The condensation experiments showed that zinc condensed as ZnO, ZnCl2, and ZnS under the conditions considered. The species detected in the gas phase were Zn, ZnO, ZnCl2, and ZnS. The experimental results were compared with Scheil–Gulliver cooling calculations carried out with FactSage 6.3 software. This model was proven to be an excellent tool for the prediction of the behavior of zinc under gasification conditions. Furthermore, the global kinetics of the condensation experiments was clarified with the thermodynamic pseudoequilibrium model recently developed by researchers of Chubu University (Japan). With this work, not only a good understanding of the behavior of the zinc under gasification conditions was obtained, but also the finding and evidence of a powerful tool for predicting fast and easily the behavior of trace metals under gasification conditions.
