などの混合ガスとして得られる。Carbon monoxide is a basic raw material of synthetic chemistry, and is produced from coke and coal by using a generation furnace, a water gas furnace, a winker furnace, a Lulgi furnace, a Koppers furnace, and the like. It is also produced from natural gas and petroleum hydrocarbons by steam reforming and partial oxidation. In these methods, the product is obtained as a mixed gas of carbon monoxide, hydrogen, carbon dioxide, methane and nitrogen.

有する。According to British Patent No. 1,318,790, a toluene solution of copper aluminum tetrachloride {Cu (AlCl 4 )} absorbs carbon monoxide when contacted with a mixed gas containing 30 mol% carbon monoxide at 25 ° C., When heated to 80 ℃, 95% of carbon monoxide is recovered. This absorption liquid has the advantage that it is not affected by hydrogen, carbon dioxide, methane, nitrogen and oxygen contained in the mixed gas and has a low absorption pressure, but it has an absorption capacity that reacts irreversibly with water. This causes deterioration and formation of a precipitate, and generates hydrochloric acid. For industrial implementation, the water content in the mixed gas must be strictly controlled to 1 ppm or less. Therefore, a strong dehydration treatment step of the mixed gas is required before the absorption step, and strict control is essential. Note that copper aluminum tetrachloride reacts strongly with water and irreversibly loses its ability to absorb carbon monoxide.
Even when a mixed gas containing pm of water is brought into contact, not only the deactivation amount gradually increases as the treatment amount of the mixed gas increases, but also the device corrosion is caused by hydrochloric acid generated by the reaction with water. It has the disadvantage of progressing. Further, when this absorbent is used, it is inevitable that toluene vapor is mixed in the recovered carbon monoxide, and that a device for removing this toluene is required, and that the liquid absorbent is used. It has disadvantages such as process restrictions.

る。There is a cryogenic separation method as a method for obtaining a large amount of high-purity carbon monoxide. This liquefies the mixed gas by cooling and liquefies between -165 and -210.
Although this is a method of fractional distillation at a low temperature of ℃, it requires complicated refrigeration / heat recovery system, uses expensive materials, requires expensive equipment, and consumes a lot of power. Furthermore, if the mixed gas contains water, carbon dioxide, etc., a clogging accident will occur in the cryogenic pipe system, so it is necessary to keep water at 1 ppm or less in the pretreatment facility.
