Selective Catalytic Reduction (SCR) Catalyst

Release time:2019-04-26 18:04


Functions& Uses

SCR catalyst isprimarily utilized for the purification of NOx from diesel exhaust gas viaammonia selective catalytic reduction technology. The catalytic reactionequation is as follows:

--- There are two main categories of SCR catalysts for commercial diesel engines, V-SCR catalyst and molecular sieve SCR catalyst. The V-SCR catalysts can comply with diesel road National IV and National V emission standards. The molecular sieve SCR catalyst is further sub-divided into Cu-SCR and Fe-SCR, which are mainly applied to road diesel National VI and non-road diesel National IV emission standards and above;

--- SCR catalyst is also applied for treatment of NOx for vessels and stationary sources.

Performance Characteristics

--- V-SCR catalyst features superior sulfur resistance and high conversion efficiency from 250°C to 450°C

--- Cu-SCR catalyst exhibits excellent activity of low temperature and high stability of temperature hydrothermal

--- Fe-SCR catalyst is characterized by outstanding activity of medium and high temperature.
