Beschreibung
Zusammenfassung:	The present invention provides a hydrocarbon adsorption device 10 that circulates a fluid and adsorbs hydrocarbons in the fluid. The hydrocarbon adsorption device 10 comprises: a first hydrocarbon adsorption unit 20 that contains a zeolite; and a second hydrocarbon adsorption unit 30 that contains a zeolite and is disposed on the downstream side of the first adsorption unit 20 in the fluid flow direction. The pore diameter P1 of the zeolite contained in the first hydrocarbon adsorption unit 20 is smaller than the pore diameter P2 of the zeolite contained in the second hydrocarbon adsorption unit 30 (i.e., P1
