氢化反应是地球上电子和质子流动的主要途径。氢化作用是地质学和有机化学的结合，在地球的全球地球化学循环中占据着关键的位置。当今地球上氢化反应的一些例子包括在非生物和生物反应中产生和消耗甲烷，在水热环境中减少质子，以及脂肪酸的生物合成和降解。氢化反应可能对早期地球上的生命前化学很重要，今天作为基本反应类别之一，使细胞生命能够构建生物分子。对氢化反应的理解和认识有助于理解我们星球上分子和物质相互转化的更大网络。在这篇简短的综述中，我们详细介绍了与地质、生物、工业和大气化学有关的一些重要的加氢和脱氢反应。这些反应的影响范围从早期地球上的一系列反应到工业应用，如碳氢化合物燃料的生产。
Abstract Hydrogenation reactions are a major route of electron and proton flow on Earth. Interfacing geology and organic chemistry, hydrogenations occupy pivotal points in the Earth’s global geochemical cycles. Some examples of hydrogenation reactions on Earth today include the production and consumption of methane in both abiotic and biotic reactions, the reduction of protons in hydrothermal settings, and the biological synthesis and degradation of fatty acids. Hydrogenation reactions were likely important for prebiotic chemistry on the early Earth, and today serve as one of the fundamental reaction classes that enable cellular life to construct biomolecules. An understanding and awareness of hydrogenation reactions is helpful for comprehending the larger web of molecular and material inter-conversions on our planet. In this brief review we detail some important hydrogenation and dehydrogenation reactions as they relate to geology, biology, industry, and atmospheric chemistry. Such reactions have implications ranging from the suite of reactions on early Earth to industrial applications like the production of hydrocarbon fuel.
