Research on Purification Performance of Diesel Exhausts Four-Effect Catalytic Purification System

Abstract:

A test methodwas designed to evaluate the purification performance of Diesel exhausts four-effect catalytic purification system which was based on the oxidation catalyst, NOx reduction catalyst and carbon particles combustion catalyst.Then the method was usedto test the purification performance of a four-effect catalytic purification systemconsist of DOC,CDPF andSCR. The results of the test show that, with the use of the four-effect catalytic purification system, the combustion T₅₀of the soot can reach 330 ~ 400 °C which shows that the combustion of the soot has been catalyzed effectively.The rate of the deoxidized NO can achieve 90% abovewhich shows thatthe selective deoxidation of the NOx has been catalyzed effectively.
