Title:
GAS ADSORBENT, DEODORANT FIBER SHEET, AND METHOD FOR PREPARING GAS ADSORBENT
Document Type and Number:
WIPO Patent Application WO/2019/151283
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a gas adsorbent which has excellent adsorption performance for low-boiling point aldehydes and also has excellent performance for suppressing the desorption of low-boiling point aldehydes and low-polar gases from a gas adsorbent, once the low-boiling point aldehydes and the low-polar gases have been adsorbed onto the gas adsorbent. This purpose is achieved by providing a gas adsorbent containing: a proton-type Y zeolite; and a water-soluble acid hydrazide compound, wherein the proton-type Y zeolite contains SiO2 and Al2O3, and the molar ratio of SiO2 to Al2O3 contained (mole of SiO2 contained/mole of Al2O3 contained) therein is 2-20.
