Specifications

CAS-KR DeNOx Catalyst is applied in SCR Denitrification process, which is applied extensively at thermoelectricity factories, coal-fired power stations, gas turbines, internal combustion engines, waste incineration, steel factories, petrochemical industry and so on.

CAS-KR SCR Catalyst is a homogeneous product, which is made of porous metal oxide and active metal. The main backing material of catalyst consists of TiO2, V2O5, WO3 and so on.

SCR Catalyst Reaction Principle

Nitrogen oxides react with redactor, such as ammonia, forming nitrogen and water, the empirical equations for the reactions are as follows:

4NH3 + 6NO → 5N2 + 6H2O
8NH3 + 6NO2 → 7N2 + 12H2O

SCR Catalyst characteristics

  • Adopting the optimum minute pore dimension, which makes denitrification performance and abrasion resistance to obtain optimal condition.
  • To get steady denitrification performance by optimum minute pore distribution.
  • Adopting optimum active ingredients, which can restrain effectively SO2/SO3 rate while guaranteeing denitrification rate.
  • Restraining effectively SO2/SO3 rate rising in operation by adding third ingredients. 
  • Activities are even. If the surface is abraded, the activities of the rest will not be changed.
  • Low Resistance, economize the movement expenses.
  • High activity, NOx high purification efficiency
  • High water resistance
  • High erosion resistance
  • High mechanical strength and thermal resistance
