Study of isotopic effect for hydrogen and deuterium adsorption on nanoporous carbon (NPC) at 67-78 K

Abstract

Adsorption isotherms of pure hydrogen and deuterium on samples of nanoporous carbon (NPC) have been determined at range of temperature 67-78 K. Distinction in sorption abilities of nanosorbent in relation to deuterium and to hydrogen has been fixed. Adsorption capacity of the NPC samples relative to deuterium in range of pressure 0-100 kPa is larger than one to hydrogen, and both values are considerably larger than values of hydrogen isotopes adsorption capacity on common sorbents such as zeolites and active carbons. © 2007 Springer.
