    Abstract : With a growing concern to lower greenhouse gas emissions from road transportation, lean burn and diesel engines will keep playing an important role in the future. Development of a highly efficient and durable process to reduce NOx to N2 becomes a challenging issue especially in the presence of ample O2 concentration as in lean burn exhaust. READ MORE

  3. 3. Preparation and characterisation of perovskite and noble metal promoted oxide based catalysts

    University dissertation from Stockholm : Stockholms universitet

    Author : Leif Dahl; Stockholms universitet.; [1997]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICINE Chemistry; MEDICIN Kemi; Inorganic Chemistry; oorganisk kemi;

    Abstract : This work concerns efforts to improve or replace noble-metal based catalysts used for car exhaust purification. Various oxide based catalysts have been prepared by impregnating washcoats such as (-Al2O3 and SiO2 with appropriate metal ions, and assemblies calcinated at elevated temperatures have been tested for catalytic activity in the oxidation of CO and C3H6 and reduction of NO.
