Pt + Cu-loaded ZrPILC tested in the reactions of NOx selective catalytic reduction by propylene and decane in realistic feeds with a high content of water, oxygen and an admixture of SO2 demonstrated promising performance at high space velocities (up to 100 000 h−1) in the temperature range of 150–400 °C. A strong promoting effect of water, oxygen and the catalyst presulfation on the degree of NOx conversion into N2 was revealed. The specificity of these catalyst action in realistic feeds was explained by taking into account the textural, structural and surface features of zirconia-pillared clays as well as the mechanism of NOx HC SCR reaction including participation of strongly bound species in key stages.
