The aim of present work is to study the effect of copper addition on the properties of γ-Al2O3 supports for chromia catalysts for dehydrogenation of light paraffin hydrocarbons. A series of supports 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. It was shown that the addition of copper led to formation of two states of copper, i.e. oxides (CuO, Cu2O) and aluminate (CuAl2O4). The increase in the loading of copper led to growth of amount of both states.
