A low-cost denitration catalyst and its manufacturing process

Abstract

The invention discloses a low-cost denitrification catalyst and its manufacturing process. The components of the catalyst include: nano-TiO2 powder, montmorillonite, ammonium metatungstate, ammonium metavanadate, chopped glass fiber, and broad-leaved forest wood pulp Fiber, Carboxymethyl Cellulose, Polyethylene Oxide, Stearic Acid. The steps of the manufacturing process include: dissolving ammonium metavanadate with an aqueous solution of monoethanolamine as a solvent, dissolving ammonium metatungstate in water at room temperature, and stirring continuously for 1 hour for later use; fully kneading the catalyst raw materials to obtain plastic mud, and placing Store it in a closed plastic bag for several hours for aging, shape the mud into a honeycomb catalyst body, and dry the honeycomb body into a mesh belt tunnel kiln for roasting. The final product after roasting is cut according to the required length and assembled in the In the module box and outer packaging. The invention has low cost, effectively improves the denitrification performance, increases the mechanical strength of the product, and improves the wear resistance strength.

Description

technical field [0001] The invention belongs to the field of catalyst manufacturing, in particular to a low-cost denitration catalyst manufacturing process. Background technique [0002] my country's energy structure is dominated by coal, and the nitrogen oxides produced by coal burning are one of the main sources of air pollution. It will not only cause acid rain, photochemical smog and other problems that damage the earth's ecological environment, but also seriously harm the human body. health. As my country pays more and more attention to environmental protection, national and local environmental protection departments have stricter controls on the discharge and total amount of pollutants, especially the "Emission Standards of Air Pollutants for Thermal Power Plants" (GB13223-2011, January 2012 Implementation) clearly stipulates that the emission limit of nitrogen oxides from coal-fired boilers is 100mg / Nm 3 , Only using low-nitrogen combustion technology can no longer me...
