Development of an Artificial Hydrothermal System for Organic/Inorganic Synthesis

9800147 Holloway这笔拨款为建造一个配备光纤观测系统的实验室规模的人工海底热液系统的费用提供部分支持。该装置将用于验证海底热液系统可以从热液流体中溶解的碳酸盐中非生物地产生小有机分子的假设。该系统将模仿自然界中发现的黑烟通风口，能够在250巴的压力下连续向寒冷的海水中注入400摄氏度的热液。光纤观察系统将允许观察通风口和改进样品收集。位于海水容器中的采样管将在热液喷口上方的不同距离上移动，以便对一系列海水-热液流体混合比进行采样。该系统还将增加温度和压力的计算机控制和自动数据采集。＊＊＊

9800147 Holloway This grant provides partial support for the costs of constructing a laboratory-scale, artificial seafloor hydrothermal system equipped with a fiber optic viewing system. This apparatus will be used to test the hypothesis that seafloor hydrothermal systems can abiotically generate small organic molecules from the dissolved carbonate in hydrothermal fluids. The system will mimic black smoker vents found in nature, enabling continuous injection of a 400 C hydrothermal fluid into cold seawater at a pressure of 250 bars. The fiber optic viewing system will allow observation of the vent and improve sample collection. Sampling tubes located in the seawater vessel will be moveable at various distances over the hydrothermal vent in order to sample a range of seawater-hydrothermal fluid mixing ratios. Computer control of temperature and pressure and automatic data collection will also be added to the system. ***
