  1. 1. FTIR Studies and Kinetic Modelling of NOX Reduction and NOX Storage

    Författare :Björn Westerberg; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NOX storage; kinetic modelling; diesel exhaust; alumina; NOX reduction; FTIR spectroscopy; catalysis;

    Sammanfattning : FTIR spectroscopy and kinetic modelling have been used to study catalysts for NOX reduction and NOX storage. For Pt/Al2O3 exposed to NO, oxygen and propene IR-bands associated with nitrates, acetate, formate, carbonates and isocyanate were observed. Experiments with NO, oxygen and HNCO showed that isocyanate is an intermediate for reduction of NOX. LÄS MER
