Natural gas combustion catalysis Modified Activated Alumina Powder

Product Specification

Factory supply modified alumina for automobile exhaust

  The exhaust gases emitted from internal combustion engines usually contain hydrocarbons, carbon monoxide, carbonyl compounds, etc., resulting from partial or incomplete combustion of fuels, and nitrogen oxides produced by the reaction between oxygen and nitrogen gases contained in the air used for the combustion of fuels at elevated temperatures.From a view point of preventing air pollution caused by the emission of these noxious compounds, it is required to render the exhaust gases harmless by oxidizing carbon monoxide, hydrocarbons, etc.

【Application】

(1) Purification and catalysis of automobile and motorcycle exhaust gas;

(2) Industrial organic waste gas purification and indoor air purification;

(3) Natural gas combustion catalysis.

(4) Fluid catalytic cracking in oil refining industry.

【Specification】

【Product features】

  The first coat includes a stabilized alumina support on which a first platinum catalytic component is dispersed and bulk ceria, and may also include bulk iron oxide, a metal oxide (such as bulk nickel oxide) which is effective for the suppression of hydrogen sulfide emissions, and one or both of baria and zirconia dispersed throughout the first coat as a thermal stabilizer

  The second coat may also include a second rhodium catalytic component, and optionally, a third platinum catalytic component, dispersed as an activated alumina support. The present invention also provides a method for treating engine exhaust gases by contacting the gases under conversion conditions with the catalyst composition.

(1) High temperature resistance and high aging ability: the modification of lanthanum oxide can inhibit the sintering of -Al2O3 and improve the high temperature anti-aging ability of the products.

(2) High solubility index and viscosity: the modified alumina is easy to gel solution and has high viscosity, which can reduce or not use aluminum sol, improve the coating performance and reduce the shedding rate.

(3) The particle size distribution is moderate: the medium diameter of the material is controlled to be 3-6 μ m and the particle size distribution is narrow.

(4) Good product stability: advanced production technology and production equipment, standardized management, to ensure the stability of the product.
