The aim of present work is to study the effect of copper addition on the properties of chromia-alumina catalysts for dehydrogenation of light paraffin hydrocarbons. A series of chromia-alumina catalyst with different loading of copper (0.5-5%) was prepared using a successive impregnation technique. The synthesized samples were characterized by low-temperature N2 sorption, XRD, H2-TPR and UV-vis spectroscopy. Catalytic properties of the obtained catalysts were studied in the non-oxidative dehydrogenation of isobutene to isobutylene. It was shown that the addition of copper led to change ofporous structure of catalysts and provided to the growth of catalytic activity and selectivity.
