SCR Mechanism: Experimental Set-up and Procedures

This lecture covers the Selective Catalytic Reduction (SCR) mechanism using V2O5/TiO2 promoted with WO3. It explains the SCR process involving NO, NH3, O2, N2, and H2O. The instructor demonstrates the experimental set-up, including the source, spectrometer, cell, Pt, valve, and gas analyzer. The procedures involve mounting the cell, heating, cooling, filling liquid nitrogen, signal optimization, background acquisition, NH3 adsorption, reaction with NO, and NO desorption. Students are guided through questions related to interpreting IR spectra, NH3 consumption, and NO adsorption on the catalyst surface.
