The isotherms of molecular hydrogen adsorption in slit pores have been calculated at room temperature ( T = 298 K) for various pore sizes, from 0.6 nm to 2.5 nm. The pressure has been varied from 0 to 120 bar (12 MPa). The wall surface has been characterized by different values of the adsorption energy, from 3 to 25 kJ/mol. The provided raw data give the number of molecules adsorbed per nm 2 of the adsorbing wall, and can be used for fast storage capacity screening of new porous adsorbents with known
