Document Type and Number:
WIPO Patent Application WO/2024/060354
Kind Code:
A1
Abstract:
An adsorbent, which comprises a mineral matrix for removing interlayer water and a polymer adsorption body coating the outside of the mineral matrix, wherein the polymer adsorption body comprises an alcohol salt group. The adsorbent has a good adsorption effect on water, i.e. an impurity, in ammonia gas by means of a physical and chemical dual-combination effect between the polymer adsorption body and the mineral matrix for removing interlayer water.
