✦ Synopsis

Adsorption isotherms

of N, 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 Nz 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 (d,,J of the graphitic structure on the simulated N, adsorption isotherm was examined. The observed dooz of activated carbon fiber (ACF) well simulated the experimental result.
