氧气作为人类未来在月球上生存的基本条件,研究制取方法是月球基地建设中的一个主要目标。本文分类总结了利用月球含氧矿物制氧方法;就制氧方法适合就地利用月球资源、反应的高效率、反应过程易实现性等方面比较了各类方法的优缺点,提出就地利用微波能加热、氢气作为还原剂、月壤中钛铁矿作为反应物的月球基地制氧的优选方案。
Oxygen is a fundamental requirement for human to live on the Moon. Oxygen preparation is one of the major objectives in lunar resource utilization. It will be a more cost-efficient method to extract oxygen from lunar soil compared with transporting it directly from the Earth. The explorations had showed that there are various metal oxides and silicates with oxygen contents up to about 40% in lunar soil, which makes oxygen extraction from lunar soil possible. This paper summarized different oxygen extraction methods using reduction agents and heating technology. Microwave, which is a rapid and effective heating method, has many advantages over other traditional heating techniques. Therefore, this paper recommended microwave heating as the preferring heating method for speeding reduction reactions of oxygenous minerals to prepare oxygen on the Moon. Further study is much required.
