摘要: Abstract The Monte Carlo method was used in its grand ensemble variant (GCMC) combination with CO2 experimental isotherm data at ambient temperatures (298 and 308 K), order to characterize microporous carbons obtain the corresponding slit cylindrical pore size distributions (PSD). In particular, densities 298 308 K, inside single, slit-shaped as well cylindrical, graphitic pores of given dimensions were found on basis GCMC for pressures ranging from 1 10 bar. Significant differences adsorption characteristics observed attributed different molecular packing originating confinement geometries. Consequently, optimal PSDs slits cylinders which best match is obtained between computed measured isotherms determined. Comparisons made same carbon sample geometries, conclusions concerning applicability reliability resulting micropore drawn.
