Truncated pore network model for the methane and hydrogen adsorption in disordered nanoporous carbons

摘要: Abstract A useful computational model is described for representing the nanoporous structure in real carbons. The gathers geometric and topological (e.g. pore connectivity deadend pores) characteristics it used to evaluate effect that porosity (ɛ) size (H) have on adsorption behavior of methane hydrogen (obtained by Grand Canonical Monte Carlo Simulation) quantified terms excess density (ρ) gravimetric storage capacity (wt.%). In general higher adsorptions are observed compared traditional models. An increase or originates a decrease ρ. 3.1 wt.% maximum amount H2 stored material e = 0.40 , H 4.89 σ ff at 77 K, which reasonably good agreement with experimental data. This quantity lower as decreases increases. results this work support some evidences suggest linear relation between carbons specific surface area.
