Carbon canister is an evaporative emission control device to prevent the release of evaporative fuel gas from gasoline tank by the gas adsorption with activated carbon. However, there is still concern that evaporative fuel gas is released into the atmosphere, even when the vehicle is parked, because of the diffusion caused by the concentration differences of adsorbed gas.
In this study, we conducted basic experiments and calculations to reveal the behavior of gas diffusion in carbon packed bed.
As a result, we understand the mass transfer phenomenon in carbon packed bed. Furthermore, the gas diffusion can be estimated by numerical calculation.
