Adsorption isotherms of molecular hydrogen are measured at 77 K in a series of AlPO alumophosphate zeolites with different microchannel sizes. The potential of the intermolecular interaction of H2 is calculated within the model of a cylindrical channel of variable size. Henry constants are calculated for this model for arbitrary orientations of the adsorbate molecules in microchannels. The experimental and calculated values of the Henry adsorption constant of H2 are compared at 77 K on AlPO zeolites. The constants of intermolecular interaction are determined for the H2-AlPO system.
