| Research Abstract |
Development of the activated carbon that has an ability of the absorption of hydrogen of> 6. 5 wt% is hurried to reserve hydrogen on the vehicles which moves with hydrogen fuel. Although the hydrogen absorption amount is reached to 2wt% using the metal alloy, the new materials which is more excellent than such metal alloy does not appear
We developed super-activated carbon with a surface area of> 2500 m^2/g. Although the hydrogen absorption ability is only 0. 6 wt% under 12 MPa at room temperature, it increased to 6. 5 wt% under 4 MPa at room temperature. In addition, the amount of hydrogen absorption increased with increasing the total volume of 1. 1 nm-micro pore. The relationship between the total volume of 1. 1 nm-micro pore and the amount of hydrogen absorption suggested that hydrogen condensed in the micro pore. That is, the amount of hydrogen absorption jump up with liquefaction. Furthermore, the activated carbon developed in this study indicated carbon dioxide absorption with an amount of 0. 7g/g under 1. 25 MPa at room temperature
The ability of hydrogen and carbon dioxide absorption of the activated carbon with surface water is lower than that of the activated carbon without surface water
