Document Type and Number:
WIPO Patent Application WO/2023/042783
Kind Code:
A1
Abstract:
Provided is a means for increasing the hydrocarbon desorption temperature in a hydrocarbon adsorbent made of zeolite. Provided is a core-shell zeolite having a core made of a first zeolite and a shell made of a second zeolite, wherein the channel diameter of the first zeolite is larger than the channel diameter of the second zeolite.
