Document Type and Number:
Japanese Patent JP6603408
Kind Code:
B2
Abstract:
Disclosed is a preparation method for a molecular sieve-multiple oxide composite integral extrusion type denitration catalyst, belonging to the technical fields of atmosphere pollution control and environment-friendly catalytic materials. The preparation method comprises: constructing an organic structure coating on the surface of a metal ion-exchanged molecular sieves and synchronously adding multiple oxide components, thus obtaining an ion-exchanged molecular sieve-multiple oxide composite denitration catalyst active component; and then mixing, kneading into paste, staling, carrying out integral extrusion forming, drying, and calcining, thus obtaining the integral extrusion type denitration catalyst. The molecular sieve-multiple oxide composite integral extraction type denitration catalyst has a denitration efficiency more than 80% at the temperature ranging from 250°C to 420°C in the presence of 10% steam and 500ppm sulfuric dioxide. According to the present invention, the application field of metal-loaded molecular sieve denitration catalysts is widened, and thus the metal-loaded molecular sieve denitration catalysts can be widely applied to the flue gas denitration of stationary sources.
