Notes:
The mechanism of diffusion in an absorbent pore was studied by applying adsorption rate data to the Damköhler equation. Most of the data were taken in the multimolecular region of the nitrogen-silica gel adsorption isotherm. Vapor-phase and adsorbed-phase contributions to the total transport were separated. Vapor-phase transport increased with temperature and was most dominant at relative pressures of 0.4 to 0.6. Adsorbed-phase diffusivities were of the order of 10-2 - 10-3 sq. cm./sec. and showed some dependence on the amount adsorbed at surface coverages greater than 1.5 molecular layers.
