PURPOSE:To accommodate the oxygen as much as possible under a pressure less than a prescribed value by using a common can on the market and by introducing oxygen or oxygen-rich air under a pressure lower than 10kg/cm<2>G at 20 deg.C into a container filled with activated carbon. CONSTITUTION:An air-sol can filled with activated carbon is used, and filled with oxygen gas or oxygen-rich air under pressure. For example, granular activated carbon is introduced into an AE420 can having an inside capacity of 420ml, and oxygen is introduced up to a pressure of 10kg/cm<2>G at 20 deg.C. Then, oxygen is discharged by opening a valve, and then 10.5l oxygen is obtained. In other words, oxygen in 2.5 times per space volume can be accommodated. When the oxygen having a purity close to 100% is used, it reacts with activated carbon particularly in the preservation at high temperature, and CO2 or CO gas is formed. |
