Grand canonical Monte Carlo simulation for nitrogen adsorption in graphitic slit micropores: effect of interlayer distance Original Research Article

Adsorption isotherms of N2 by slit-shaped graphitic micropores at 77 K were simulated using grand canonical Monte Carlo (GCMC) simulation and compared the simulated isotherms with experimental adsorption isotherms of N2 on pitch-based activated carbon fibers. The pore was modeled as the slit space between parallel smooth graphite surfaces. The concept of the effective pore width which can be determined experimentally was used for the simulation. The effect of the layer distance (d002) of the graphitic structure on the simulated N2 adsorption isotherm was examined. The observed d002 of activated carbon fiber (ACF) well simulated the experimental result.
