    • An improved method for purifying gaseous mixtures of germanium hydrides and hydrogen is disclosed. In one aspect, the crude gas is contacted with a cold caustic solution to reduce levels of carbon dioxide and water. The partially purified gas is chilled in direct-contact with a hydrogen refrigerant to induce homogenous condensation of water impurity. Liquid and ice particles formed by lower temperatures are removed across an aerosol phase separating medium to produce a cooled and partially purified gas mixture which is further dried and de-carbonated across a zeolitic molecular sieve adsorbent to achieve very low concentrations of moisture and carbon dioxide in the bulk gas. In one aspect, the purified gas mixture obtained is partially liquefied, phase-separated and distilled to obtain germanium hydride, digermanium hexahydride and hydrogen gas as products. A portion of the hydrogen product can be compressed, chilled and re-used as a direct-contact refrigerant in the purification process.
    • 公开了一种用于纯化氢化锗和氢气的气态混合物的改进方法。 在一个方面,粗气体与冷苛性溶液接触以降低二氧化碳和水的含量。 部分纯化的气体与氢制冷剂直接接触而冷却,以引起水杂质的均匀冷凝。 通过气溶胶相分离介质去除由较低温度形成的液体和冰颗粒,以产生冷却和部分纯化的气体混合物,该气体混合物进一步在沸石分子筛吸附剂上干燥和脱碳,以实现非常低浓度的水分和二氧化碳 大量气体。 一方面,将获得的纯化气体混合物部分液化,分相分离并蒸馏,得到氢化锗,六氢六氢呋喃和氢气作为产物。 在纯化过程中,氢产物的一部分可以被压缩,冷却并重新用作直接接触制冷剂。
