ABSTRACT:
A process and system for the synthesis and/or purification of crude germane to provide a purified germane product are disclosed herein. In one aspect of the present invention, there is provided a process for making a purified germane product containing less than 1 volume percent of one or more germanium-containing impurities comprising: providing a crude germane fluid; passing at least a portion of the crude germane fluid through a first adsorbent which selectively adsorbs water and carbon dioxide contained therein and withdrawing therefrom a partially purified germane fluid; passing at least a portion of the partially purified germane fluid through a second adsorbent which selectively adsorbs the one or more germanium-containing impurities contained therein and withdrawing therefrom a hydrogen-enriched purified germane fluid; and separating the purified germane product hydrogen from the hydrogen-enriched purified germane fluid.
