Modified Activated Carbon as an Effective Hydrogen Adsorbent

Hydrogen adsorption measurements were taken by the weighting method using Sartorius low-pressure microbalance. Experiments conducted at two temperatures: 77.5 and 300 K; adsorbent used was active carbon obtained from wood modified with potassium hydroxide. The porous structure of prior to after modification evaluated based on nitrogen desorption data. Thus, densimetric characteristic modified; structures developed in range micro-, meso- macropores volume hydrogen adsorbed K showed an almost four-fold increase. Modified carbons are found be suitable for applications storage systems.
