Serpentinization refers to the alteration of ultramafic rocks that produces serpentines and secondary (hydr)oxides under hydrothermal conditions. Serpentinization can generate H2, which in turn can potentially reduce CO/CO2 and produce organic molecules via Fischer–Tropsch type (FTT) and Sabatier type reactions. Over the last two decades, serpentinization has been extensively studied in laboratories, mainly due to its potential applications in prebiotic chemistry, origin of life in extreme environments, development of carbon-free energies and CO2 sequestration. However, the production of H2 and organics during experimental serpentinization is hugely variable from one publication to another. The experiments span over a large range of pressure and temperature conditions, and starting compositions of fluid and solid phases are also highly variable, which collectively adds up to more than a hundred variables and leads to controversial results. Therefore, it is extremely difficult to compare results between studies, explain their variability and identify key parameters controlling the reactions. To overcome these limitations, we collected and analysed 30 peer-reviewed articles including over 100 experimental parameters and ca. 30 mineral and organic products, hence building up a database can be completed and implemented in future studies. We then extracted basic statistical information from this dataset and demonstrate how such a comprehensive dataset is essential to better interpret available data and discuss the key parameters controlling the effectiveness of H2, CH4 and other organics production during experimental serpentinization. This is essential to guide the design of future experiments.

实验蛇纹石化过程中 H2、CH4 和有机化合物形成的数据集

蛇纹石化是指在热液条件下产生蛇纹石和二级(氢)氧化物的超基性岩蚀变。蛇纹石化可以产生 H 2,这反过来又可以潜在地减少 CO/CO 2并通过费托型 (FTT) 和 Sabatier 型反应产生有机分子。在过去的二十年中,蛇纹石化在实验室中得到了广泛的研究,主要是由于其在益生元化学、极端环境中的生命起源、无碳能源的发展和 CO 2封存方面的潜在应用。然而,H 2 的产生实验蛇纹石化过程中的有机物在不同出版物之间变化很大。实验跨越大范围的压力和温度条件,流体和固相的起始成分也高度可变,加起来总共有一百多个变量并导致有争议的结果。因此,比较研究之间的结果、解释其可变性并确定控制反应的关键参数是极其困难的。为了克服这些限制,我们收集并分析了 30 篇同行评审文章,其中包括 100 多个实验参数和大约。30种矿物和有机产品,因此建立一个数据库可以在未来的研究中完成和实施。2、实验蛇纹石化过程中CH 4和其他有机物的产生。这对于指导未来实验的设计至关重要。
