摘要：
A mass spectrometer (MS) and a novel UV analyzer were coupled in the experimental study of the transient Selective Catalytic Reduction (SCR) reactivity, aimed at the development of a dynamic numerical model of SCR converters for the selective reduction of NO (x) in Diesel exhausts. Their parallel use revealed an effective method for the understanding of key elements in the SCR reaction mechanism under real operating conditions.
