Plate type denitration catalyst and preparation method thereof

Abstract

The invention relates to a plate type denitration catalyst and a preparation method of the catalyst and belongs to the field of environment-friendly catalysis material and air pollution control. A cerium-antimony-molybdenum composite oxide serves as a catalytic active component; a tungsten, cobalt or lanthanum oxide serves as a promoter; a titanium dioxide and argil mixing component serves as a major carrier; mass percentages of the cerium-antimony-molybdenum composite oxide and the promoter oxide are 8-20% and 1-3% respectively by taking the mass of the titanium dioxide and argil mixing component carrier as a reference. The denitration activity of the catalyst reaches 98.5% or above, and the catalyst has excellent sulfur poisoning resistance.

Description

Technical field

[0001] The invention relates to a plate-type denitration catalyst and a preparation method thereof, belonging to the field of environmental protection catalytic materials and air pollution control. Background technique

[0002] In recent years, the state has strengthened supervision of denitrification catalysts (vanadium-titanium series), encouraged the promotion of rare-earth-based denitrification catalysts, provided space for new catalysts, and encouraged enterprises to use rare-earth-based denitrification catalysts to replace vanadium-titanium denitrification catalysts, while reducing waste smoke from the source The production of gas denitrification catalysts (vanadium-titanium series) strives to reduce the amount of hazardous waste produced nationwide and promote the use of light rare earths.

[0003] At present, based on the total installed capacity of thermal power industry of 880 million kilowatts, 600 float glass furnaces, and more than 6000 ceramics industr...
