Title:
PRODUCTION OF CATALYST FOR PURIFYING EXHAUST GAS
Document Type and Number:
Japanese Patent JP3236040
Kind Code:
B2
Abstract:
PURPOSE: To enhance the NOx purifying capacity of a catalyst for purifying exhaust gas by enhancing the support amount of the metallic active sead on a porous material.
CONSTITUTION: A catalyst agent wherein a metallic active seed is supported on a porous material and an acidic binder are slurried so that a slurry is made basic.
