Autoignition of n-Decane Could it be a Benefit for the Selective Catalytic Reduction of NO?

The effect of void volume (apparent residence time variation) on oxidation of n-decane and on the n-decane-SCR of NO was studied on Ag/AlO with a silver loading of 2 wt% and on Cu exchanged Y zeolite. A positive effect on the reduction of NO was observed and the better result was observed occurring with a moderate autoignition of n-decane, which corresponds to an intermediate apparent residence time.
