Abstract

The porous structure of activated carbon modified by successive removal of external layers from a granule surface as produced by abrasion in a spouted bed was investigated. Procedure used for activated carbon modification is the way to minimization voids and macropores without decreasing the volume of adsorbing pores. The concept of hydrogen adsorption storage in modified samples was analysed. The amount of hydrogen that can be stored in an adsorption system depends on the hydrogen volumetric uptake and densimetric characteristics. The results show that the cryoadsorption technique could provide a viable method for hydrogen storage.
