Abstract: FTIR-PAS was used for the structural study of carbonaceous material on the surface of tungstosilicic acid which is a catalyst for the oxidative dehydrogenation of ethylbenzene. It turns out that the carbonaceous material contains conjugated double bonds and carbonyl groups.

Key words: Oxidative dehydrogenation of ethylbenzene, Tungstosilicic acid, Infrared photoaceous spec-trometry, Carbonaceous material
