Ceramic Catalyst For Nox Oxidation

These filters achieve nox removal with over 90 efficiency.

Ceramic catalyst for nox oxidation.

Honeycomb scr catalyst 1 scr technology is a recation at use of the denitration catalyst at a certain temperature 270 400 degree that nox in the flue gas mixed with ammonia gas from the reducing agent supply the system after the occurence of the selective catalytic reduction reaction of nitrogen and water thereby reducing nox emissions and reducing smoke pollution to the environment. Catalytic oxidation is one of the many options you have when looking at air pollution control systems at your facility. Automotive honeycomb ceramic catalyst is used for straight ceramic catalyst substrate for engine exhaust gas purification system. Liqtech supplies oxidation catalysts in cordierite or metal for both automotive and non automotive applications.

An example of nscr is with engine emission control such as automobile catalysts. Tuning the engine to have a stoichiometric balance of co hydrocarbon and nox compounds allows a 3 way catalyst typically a mixture of pt pd rh to simultaneously remove all three target compounds nox co and the hc. For the diesel on and off road segment we offer a variety of pre catalysts for diesel particulate filters dpf systems.

For no x removal by selective catalytic reduction scr a catalytic coating based on a tio 2 v 2 o 5 wo 3 catalyst system was developed on a ceramic filter element. Catalysts are used to reduce the oxidation temperature resulting in lower operating costs through the reduction of fuel needed to heat an air pollution control system. Coated the catalyst on the substrate surface by high geometric surface area of contact and low heat capacity improving catalyst performance when the car exhaust through the catalyst the exhaust hc co no and other harmful ingredients into harmless components. Different tio 2 sols of tailor made mean particle size between 40.

The development of a catalytically active filter element for combined particle separation and no x removal or voc total oxidation respectively is presented. However they are incapable of reducing no x to n 2 and o 2 as occurs in three way catalysts because reduction reactions will not take place under the lean conditions at which an oxidation catalyst is used. The catalysts can be designed to remove co hc and for rich operation in gas engines which also includes nox.
