摘要: A volumetric apparatus for adsorption measurement of hydrogen in carbonaceous materials aimed at storage was constructed. The performance the assessed by helium and one kind vapor-grown graphitic nanofiber (GNF). bulk gas amounts determined equations state Modified-Benedic-Webb-Rubin (MBWR), ideal Soave-Redlich-Kwong (SRK) under conditions present study are compared. Two different methods processing experimental data to determine residual volume studied. Experimental results theoretic analysis showed that method described this paper could accurately Gibbs excess amount materials. Although GNF used did not show a significant capacity hydrogen, obtained would provide favorable reference development material storage.
