通过实验获得了填炭纸在液氮温度下对N2和H2两种气体的等温吸附线,结果表明:填炭纸对N2的吸附效果非常好,对H2的吸附效果较差,相同平衡压力下对N2的吸附量比对H2的吸附量高出1~2个数量级,且在填炭纸外包上绝热材料能大大提高其对气体的吸附能力,尤其是对N2的吸附量能提高1~2个数量级,对H2的吸附量也能提高1倍以上,填炭纸对H2的吸附效果是活性炭的3~15倍。用Temkin吸附式对等温吸附线进行拟合,得到了填炭纸在10-4~10Pa范围内适用的对N2和H2两种气体的等温吸附方程式。
The adsorption isotherm of N2 and H2 gas at different temperature of liquid nitrogen was obtained by experiments. The results show that the adsorption of N2 on carbon paper is very good and the adsorption effect on H2 is poor. Under the same equilibrium pressure The adsorption capacity of N2 is 1 ~ 2 orders of magnitude higher than the adsorption capacity of H2, and the adiabatic material coated with carbon paper can greatly enhance the adsorption capacity of gas, especially the adsorption amount of N2 can be increased by 1 ~ 2 An order of magnitude, the amount of H2 adsorption can also be increased more than 1 times, carbon paper on the adsorption of H2 is 3 to 15 times the activated carbon. The adsorption isotherms of N2 and H2 were obtained by fitting Temkin adsorption on isothermal adsorption line.
