▎ 摘  要

NOVELTY - Preparation of corrugated plate type denitration catalyst comprises mixing graphene, nano-titanium dioxide, porous molecular sieve, molybdenum trioxide, tungsten trioxide, ammonium metavanadate, oxalic acid and water to obtain a mixed solution; adjusting the pH of the mixed solution at 6-7 using ammonia water, and stirring, standing and dehydrating to obtain denitration catalyst slurry having solid content of 80-90 wt.%; curing, mixing the cured denitration catalyst slurry with ethylene-vinyl acetate copolymer and glass fiber to obtain denitration catalyst mud material; stamping and forming to obtain a corrugated sheet; spraying resin glue in corrugated sheets, laminating and assembling to obtain a corrugated plate type denitration catalyst blank; and firing. USE - The method is for preparation of corrugated plate type denitration catalyst (claimed). ADVANTAGE - The composite carrier of porous molecular sieve, graphene and titanium dioxide is used as an active material carrier, which has high adsorbability, can actively adsorb reactants to perform active catalytic reduction reaction, can load more active components to excite the activity of the active materials and improve the activity of the corrugated plate type denitration catalyst, and is combined with the active components of molybdenum trioxide, tungsten trioxide and ammonium metavanadate, so that the obtained catalyst is slightly influenced by temperature and can adapt to wider use conditions, where active temperature range is 120-280 degrees C. The catalyst has an integral structure and high strength. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for corrugated plate type denitration catalyst.
