Abstract

The intersecting capillaries model (ICM), combined with the Monte Carlo simulation approach, was applied to characterize a computer-generated microporous "model carbon" with known structure, in order to evaluate the realism of this characterization method. The "partial" PSDs for three species (CH4, CF4 and SF6) were obtained by comparing the Monte Carlo simulated isotherms in the slit pores of the ICM with the isotherms generated from the model carbon. There is good agreement between model carbon-generated isotherms and the isotherms predicted based on the overall PSDs (by combining the partial PSDs). The overall PSD agree well with the real PSD of the model carbon in their dominant pore size range. These results support the validity and the realism of this characterization method for the characterization of porous carbons.
