摘要:氧气是人类生存必不可少的物质,也是传统火箭引擎的燃烧推进剂。如果能在诸如月球之类的外太空原位制取氧气,将为人类深空探测提供呼吸气体及飞行器燃料保障。本文综述了几种从月壤中提取氧气的方法,这些方法包括传统的化学还原法、硫酸处理法、气相高温裂解法、等离子高温分离法、熔盐电脱氧和熔融月壤电解法。重点介绍了熔融月壤电解工艺的制氧方法,利用月壤原材料制取氧气和金属或合金,实现最大程度的原位资源利用。同时比较各类方法的优缺点,提出熔融月壤电解法为实现月球制氧的优选方案。

In-situ oxygen generation on the Moon
Abstract:Undoubtedly, Oxygen, a fundamental requirement for human to live, which is the most significant component in any bi-propellant space rocket required. Therefore,it is vital that locally produced oxygen is available from Moon; to enable provide breathing gas and space rockets refuel for more viable space exploration to more distant regions of solar systems, and beyond. This paper reviews different oxygen extraction methods from lunar regolith, such as chemical reduction of the metal oxides, sulphuric acid of the metal oxides, high temperature fusion of the metal oxides, and evaporation of the metal-oxide and electrolysis. Herein it is important introduces that the process steps needed to generate the desired oxygen product, and a metal by-product, on the Moon, to come true maximum level of In-situ Resource Utilization for the Molten salt electrolytic. Compared with advantage and disadvantage of the methods, it is the best way to obtain a high purity oxygen product of Molten salt electrolytic on the moon.
