Beschreibung
Zusammenfassung:	The present invention provides a hydrocarbon adsorption device 10 configured to circulate a fluid and adsorb hydrocarbons in the fluid. The hydrocarbon adsorption device 10 includes a first hydrocarbon adsorption section 20 containing zeolite, and a second hydrocarbon adsorption section 30 which is provided downstream of the first hydrocarbon adsorption section 20 in the flowing direction of the fluid. The pore diameter P1 of the zeolite contained in the first hydrocarbon adsorption section 20 is smaller than the pore diameter P2 of the zeolite contained in the second hydrocarbon adsorption section 30 (i.e., P1 < P2).
