Kinetics and mechanism of hydrogen adsorption in as-obtained and ground nuclear graphite
Wendelstein 7-X are examined. In the first time interval the adsorption process is determined
by dissociation of the hydrogen molecule, occurring at the outer surface and in open
micropores of nuclear graphite particles. However, in the second time interval, the slowest
step in the hydrogen adsorption is inter-granular and inter-crystallite diffusion in nanopores
of graphite. The X-ray analysis shows, that grinding of as-obtained nuclear graphite results in
finer particles with finer nanocrystals and larger density of opened pores and carbon reactive
sites. The capacity and rate of adsorption increase with comminution of nuclear graphite particles and adsorbed hydrogen does not sub stantially alter the microstructure of nuclear
graphite.
