Description
Technical field
The invention belongs to metallurgical technology field, in particular to a kind of original position extracts metal using lunar soil lunar rock and prepares oxygen
Method.The preparation that this method is expected to consumable resource oxygen and metal necessary to building for human future lunar base provides
Theory support and technical guarantee.
Background technique
Establish lunar base or outpost base station, log in Mars and the asteroid utilization of resources be always the mankind's space probation research
Hot spot and medium-term and long-term science innovation and engineering and technological research advanced subject.The moon is the nearest celestial body of liftoff ball, is praised
It is only stage which must be passed by and important terminal that the mankind march to deep space for the natural space station never fallen and spacelab.Oxygen
Gas is the necessary material of life-support systems and propellant, and a series of metals (alloy) material is construction of base and correlation
The key raw material of structure member production.Since ground-moon transportation cost is about 50000~100000/kg, local use
Menology resource prepare lunar base construction and related science research institute necessary to the basic materials such as metal and oxygen, be realize it is low at
The key point of this menology activity and serial space probation task sustainable development.
To moon remote sensing and manned moon landing's detection result show almost entire moonscape be covered with one layer it is broken by rock
Bits, powder, dust, loosely organized weathered layer --- the lunar soil for hitting the material compositions such as melten glass.Lunar soil is in strong reducing property
It is formed in environment, is mainly made of silicate mineral and oxide ore, contain anorthite, pyroxene, olivine, ilmenite and Ke Li
The mineral constituents such as Pu Yan.The granularity of lunar soil concentrates on 1cm hereinafter, showing loose and unconsolidated soil characteristic, is considered
It is the primary object that the following mankind carry out lunar base construction and lunar surveyor exploitation.In addition, menology solar energy resources abundant
With thermonuclear fusion raw material helium -3 of great application potential, metal is prepared using lunar soil for original position and oxygen has established the important energy
Ensure basis.
Currently, the method extracted metal from lunar soil or lunar soil emulation sample and prepare oxygen is broadly divided into chemical method and electrification
Method two major classes.Chemical method mainly has carbothermic method, hydrogen reduction method, chlorine reduction method and self-propagating high-temperature method etc.；And it is electrochemical
Method mainly includes acidleach-electrolysis method, molten slag electrolysis refining method, direct electrodeoxidation method, fused salt electrolysis process etc..Chemical method needs to consume big
The reducing agent of amount has that energy consumption is higher low with reducing agent original position cyclic utilization rate, and the loss of reducing agent is needed from ground
Ball supply.Electrochemical process direct extraction of metal and prepares oxygen from lunar soil composite oxides, to raw material using electronics as reducing agent
Adaptability is relatively strong and process is shorter, but there are high temperature and strong corrosive fused salt heavy corrosion reactor linings, long-life low-cost
Inertia analyses the deficiencies of challenge and molten salt electrolyte volatilization loss of oxygen anodes developing material.
Since lunar soil ingredient and structure are more complex, the composite oxides containing there are many therefrom extract gold using single method
There are many deficiencies with oxygen for category, and the original position that can not achieve truly utilizes Resource Access metal and oxygen.Have in mind not
It is next, achievable scale comprehensive utilization lunar soil extraction metal, which is developed, with the new method for preparing oxygen undoubtedly has more potentiality.
Summary of the invention
Deficiency existing for the method for metal and oxygen is prepared from lunar soil or lunar soil emulation sample for existing, the present invention provides
A kind of new method combined by vacuum thermal decomposition-two step of inert anode molten-salt electrolysis prepares oxygen and metal.Pass through first
Vacuum thermal decomposition from contain feldspar [CaAl2Si2O8, NaAlSi3O8], pyroxene [FeSiO3, CaSiO3, MgSiO3], olivine
[Fe2SiO4, Mg2SiO4] and ilmenite [FeTiO3] etc. components lunar soil or lunar soil emulation sample in, extract oxygen simultaneously obtain by-product
Low oxide Electrochemical separation is oxygen and gold by object low oxide, the method for then using inert anode molten-salt electrolysis
Belong to, realizes the purpose in situ for efficiently preparing oxygen and metal using lunar soil.
The technical solution of the present invention is as follows:
A method of it extracting oxygen and metal from lunar soil lunar rock, includes the following steps:
(1) lunar soil or lunar soil emulation sample are heated to 2000~3000 DEG C under vacuum atmosphere and keep the temperature 2~6h, make lunar soil
Or sample is vaporized and reaction of decomposing for lunar soil emulation, generates oxygen and metal suboxide, collects heat with gas collecting apparatus and divides
Solve the product oxygen of reaction；
(2) after thermally decomposing, by-product metal suboxide is collected, is added in cryolithionite fused salt, is adopted
With Fe-Ni alloy/C or Fe-Ni-Al2O3Cermet is anode, at 720~800 DEG C and 0.6~1.4A/cm of current density2Item
Under part, it is electrolysed 1~4h, by metal suboxide Electrochemical separation, obtains alloy in cathode, anode obtains oxygen；
(3) it is saved backup after the oxygen of collection being carried out purification and liquefaction processing；It simultaneously will electrolysis gained metallic product point
Batch is extracted out from electrolytic cell and cast molding, spare.
Further, the vacuum degree of above-mentioned steps (1) is 10-5~10-7Pa。
Further, LiF and AlF in the cryolithionite molten salt electrolyte of above-mentioned steps (2)3Molar ratio be 1.7~
5.66:1.
Further, by-product metal suboxide dosage accounts for molten salt electrolyte and low-valent metal in above-mentioned steps (2)
1~3wt% of oxide gross mass.
Further, the oxygen that above-mentioned steps (1) generate accounts for 15~25wt% of the gross mass of lunar soil or lunar soil emulation sample.
Further, the alloy composition of the cathode product of above-mentioned steps (2) is by mass percentage are as follows: and Si29~
39%, Ti 2~5.5%, Fe 9~14%, Al 41.5~58.5%.Pure oxygen is precipitated in anode, and anodic current efficiency is
79.61%~84.1%.
Under vacuum and hot conditions, the metal oxide component for reaction of decomposing in lunar soil or lunar soil emulation sample is main
It is silica, iron oxide, titanium oxide and aluminium oxide, the reaction equation being related to are as follows:
