Carbon deposits formed on the catalysts' surface is characterized by the different properties. This depends, among others, on the temperature of the catalytic reaction conducted. Application of FT-IR/PA (Fourier transform infrared photoacoustic) spectroscopy allows to examine the carbon deposit forms created during the reaction. Samples of the commercial KUB-3 catalyst (Ni-NiO/Al2O3) taken from the industrial bed after three-year continuous work (applied for the hydrogenation of benzene) were characterized by means of FT-IR/PAS.
