Abstract
A composition is provided that has heat resistance sufficient for use as a hydrocarbon adsorbent and desorbs hydrocarbons slowly with respect to an increase in temperature. The composition includes an alkali metal and a zeolite having a YFI structure. A content of the alkali metal is 1 to 40 mass % based on a total mass of the composition, and a content of the zeolite having a YFI structure is 99 to 60 mass % based on the total mass of the composition.
