Effect of pore size distribution shape on the prediction of binary adsorption equilibrium and kinetics of gases in activated carbon

摘要

A recently proposed model using the ideal adsorbed solution theory (IAST) and micropore size distribution (mpsd)concept to describe the multicomponent adsorption equilibrium and kinetics of gases in activated carbon is applied to study the effect of MPSD shape on the predictio performance of binary adsorption equilibrium and kinetics.The model is stest with the experimental data aof adsorption equilibrium and kinetics of mixed gases on Ajax-activated carbon.Two different MPSDs derived from different methods for Ajax-activated carbon are used.The results shown that the model can predict accurately the multicomponent adsorptin equilibrium and kinetics using only information of single-component system,and hte mpsd shape affects the equilibrium prediction weakly but plays an imprtant role in the kinetics prediction.
