Calculation Method of Adsorption and Desorption Performance of Butane Gas in Carbon Canister

This paper presents how Computational Fluid Dynamics tool can be used for the numerical evaluation of n-butane adsorption and desorption performance in carbon canister.

Formula of material balance within activated carbon particles and formula of material/heat balance within activated carbon packed beds for n-butane as a single component were used in the simulation. These formulas were derived after experiments proved that water vapor in the air do not inhibit the adsorption of n-butane.

The experiments and the formulas are described and the significance of the simulation is investigated.
