Acquisition of an Internally Heated Pressure Vessel for Hydrogen

该合同提供了购买氢气兼容内部加热压力容器所需资金的一半。该容器将安装在布朗大学地质科学系的高压和温度实验研究中。通常的压力容器设计不允许在有水的情况下在高压和高温下对岩石系统进行工作，因为水的解离会导致大量的氢，这对金属护套具有腐蚀性。但这样的实验在实验岩石学中是必不可少的，因为水在地球上无处不在。这里要求的系统将允许在模拟地球条件下对水-岩石系统进行长期实验。

This award provides one-half of the funds required for the acquisition of an hydrogen.compatible internally heated pressure vessel. The vessel will be installed for high.pressure and temperature experimental research in the Department of Geological Sciences at Brown University. The usual design of pressure vessel precludes work at high- pressure and temperature on rock systems in the presence of water because the dissociation of water can lead to considerable amounts of hydrogen which is corrosive to the metal jacket. But such experiments are essential in experimental petrology because water is ubiquitously present in the Earth. The system requested here will allow long-term experiments on water-rock systems under conditions simulating those in the Earth.
