Determination of compressibility factor and fugacity coefficient of hydrogen in studies of adsorptive storage

The compressibility factor (z) of hydrogen was evaluated from the experimen tal p-V-T data and calculated from equations of state, such as the SRK equa tion and BWR equation as well. The effect of z on the adsorbed amount calcu lated was demonstrated by the adsorption of hydrogen on SA-zeolite. The com pressibility factor and the fugacity coefficient of hydrogen were formulate d based on the experimental p-V-T data for 60-333 K and up to 25 MPa.
