在类似气化的条件下，研究了铅在气相和凝聚相之间的化学形态、浓度和分布。研究了硫化氢、氯化氢和水蒸气对铅形态的影响。用分子束-质谱仪在线测定了气态物种。用标准方法对凝析油进行分析。主要化学形态为金属铅、PbCl2和PbS。实验数据与热力学Scheil-Gulliver冷却计算结果进行了比较。此外，实验数据被用作假平衡模型的输入，该模型旨在确定关于潜在转变的动力学信息。
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.
