Abstract
PURPOSE: In producing a catalyst used for selective contact reduction of NOx in waste gas by NH3, a thin durable highly active plate type denitrification catalyst which is easy to be scaled up is provided.
CONSTITUTION: A slurry made of porous powder carrier containing active components and binder is coated on metal screen and dried to produce a plate type denitrification catalyst. As such carrier, orthotitanate or metatitanate preferred at temperatures of 600°C or higher for 0.5 to 10 hours is used. Orthotitanate is prepared, for example, by hydrolysis of TiCl4 or titanium sulphate in an aqueous alkaline solution. Metatitanate is prepared by hydrolysis of 1 titanium sulphate in warm water. The so prepared catalyst provides a large area catalytic plate reinforced by metal screen as well as a desired shape by use of honeycomb structure.
