Denitrification catalyst (DeNOx catalyst)
Description of Final products

A filter that removes nitrogen oxides (NOx) from combustion exhaust gas.

Applications

Treatment of combustion exhaust gas from facilities such as thermal power plants and waste incineration plants.

Manufacturing process

※This process is just one example, and the manufacturing methods vary by company.

Raw materials to be processed
Kneading
Various raw materials or premixed formulations are kneaded.
課題

Uniform kneading is required to ensure proper formability during the downstream extrusion molding process and after calcining. In addition, the wetted parts of the equipment must be wear-resistant against ceramic-based raw materials.

解決策

The twin-screw continuous kneader "KRC Kneader" not only enables the production of uniform and stable products by the following mechanical characteristics but also offers excellent durability and maintainability.

Excellent mixing performance achieved by the self-wiping function of the paddles

Kneading is performed with a uniform residence time distribution (plug flow).

KRCニーダ ジャケット冷却

Removal of kneading heat by cooling through the jacketed barrel

KRCニーダ 耐摩耗材

Wetted parts are made of wear-resistant materials.

Extrusion
molding
The kneaded material is formed into a honeycomb shape.
Drying
Drying is performed by using heaters or similar equipment.
Firing
Firing at high temperatures to solidify is performed.
