Catalytic Diesel Exhaust Purification. A DRIFT Spectroscopic and MechanisticStudy of Soot Oxidation

摘要

This thesis deal with catalytic oxidation of soot particulates. As the oxidationof soot occurs around 875 K, and the temperature of diesel exhaust (depedent on the loading of the diesel-engine) hardly ever exceeds 625 K, catalytic oxidation of soot is required. Three major groups of catalytically active materials are known: catalysts based on transition metal chlorides, catalysts based on alkali
