No. 22 Evaluation of Pore Structure of Activated Carbon Fiber by GCMC Method

Modeling the pore structure from the pore distribution evaluation of activated carbon fibers using the GCMC method.

In this document, we evaluate the pore structure of activated carbon fibers (ACF) with slit-type pores using the GCMC method, and based on these results, we are examining pore shape models. Using the BELSORP MAX, we measured the N2 adsorption isotherm at 77.4 K for ACF (KURACTIVE FT-07) at ultra-low relative pressure (p/p0=1E-8) (pre-treatment: 300°C, 12 h). The measured adsorption isotherm is illustrated alongside the ideal adsorption isotherm calculated using the slit and carbon N2@77.4K GCMC kernel. We encourage you to read it.
