这项工作的目的是评估 H2O、HCl 和 H2S 对锌的冷凝和释放的影响。在装有气体冷却区的熔炉中的加热流道反应器中研究了锌蒸气的冷凝行为，其中八个玻璃过滤器放置在不同的冷却阶段。通过离子色谱（IC）和电感耦合等离子体发射光谱（ICP-OES）测定沉积在过滤器中的金属物质。无机蒸气释放的实验在与分子束质谱仪（MBMS）耦合的加热流道反应器中进行。实验在两种典型的气化条件（H2/H2O/He 或 Ar）和大气压下进行，HCl 和 H2S 分别为 50 和 500 ppmv。热气分析在 900、800、700 和 500 °C 下进行。缩合实验表明，在所考虑的条件下，锌缩合为 ZnO、ZnCl2 和 ZnS。气相中检测到的物质为 Zn、ZnO、ZnCl2...
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...
