Document Type and Number:
WIPO Patent Application WO/2020/085168
Kind Code:
A1
Abstract:
Provided are a novel method for manufacturing a Cu-P co-loaded zeolite, etc., whereby a high-performance Cu-P co-loaded zeolite can be obtained at comparatively low cost by a simpler process and with little environmental burden. A method for manufacturing a Cu-P co-loaded zeolite containing at least a small-pore-diameter zeolite and non-skeletal copper atoms and non-skeletal phosphorus atoms loaded on the small-pore-diameter zeolite, wherein the method for manufacturing a Cu-P co-loaded zeolite has at least a step for preparing a Cu-loaded small-pore-diameter zeolite, and a P loading step for applying a treatment liquid containing at least phosphoric acid and an organic base to the Cu-loaded small-pore-diameter zeolite.
