With the surge in vehicle production , Automobile exhaust has become a flow source of pollution. It has very serious harm to the air. And now the main method of treatment this pollution is to install exhaust purifiers. The core of purifier is catalyst.
Now foreign is widely develop and applicate the catalyst they are mainly palladium (Pd) platinum (Pt), rhodium (Rh) and other precious metals.Although the catalyst has high activity, good purification effect , long life and other advantages ,the cost is quite high. From put the rare earths used in automobile exhaust evolution... ,this catalyst researcher are concerned about catalytic properties of rare earth oxide early. The features of rare earth complex catalysts are high activity, good thermal stability, low price , long life, especially with anti- lead poisoning characteristics , and thus more and more people 's attention.It has become widely accepted in the field of automobile exhaust .
Our rare earth complex catalyst is a composite oxide with reasonable formulation and zirconium. Its diameter only have 1 micron1. It is applied to ceramic honeycomb carrier and metal honeycomb carrier for vehicle , and ceramic honeycomb carrier for industrial waste gas treatment. It was greatly improved that because of the control to subtle structure of coating , make the High temperature deformation of alumina carrier, uniform dispersion of precious metal, aggregates and reunion of precious metal particles caused by the deformation.The product can make exhaust emission standards achieve to Euro 3 and Euro 4 standard. At the same time , it is not only reducing the precious metals ( palladium, platinum, rhodium ) with a capacity of 15-25 % , but also extend the life of aging 30000 kilometers or more. It is obvious reduce product cost for the enterprise.
2.The main characteristics of the product:
( 1 ) To avoid the traditional use of rare earth nitrate Nox gas during sintering method brings environmental pollution ;...
( 2 ) To simplify the coating process ;
( 3 ) To improve, the r -alumina to α -alumina of the temperature inversion point . In addition to the rare earth composite materials for automotive exhaust gas purification , but also for industrial waste treatment and indoor air purification ;
( 4 ) Reduce the amount of precious metal to extend catalyst life and improve catalyst activity and thermal stability .
Suitable for automobile exhaust purification catalytic converters , industrial waste gas purification and other fields. It can meet the increasing requirements of environmental protection .
Rare earth composite material has high temperature stability, storage and release oxygen , promote the dispersibility of noble metal for active component, improving the catalytic activity for catalyst anti-poisoning and other importance. It is widely used in the carrier coating material and Can significantly, reduce the activation temperature of the catalyst, improve the catalytic efficiency. The increasing environmental requirementswill bring
