С. 117-119Abstract: Two series of cromium-zirconium mixed oxide catalysts with different Cr/Zr molar ratio were prepared by co-precipitation method. Porous structure of catalysts was investigated by low-temperature N2 adsorption, phase composition and chromium state of catalysts were characterized by X-ray diffraction (XRD) and temperature-programmed reduction with H2 (TPR-H2). The mixed catalysts were studied in non-oxidative dehydrogenation of propane at 550 °C. The catalysts obtained without ageing were shown higher activity in
propane dehydrogenation due to possible higher content of reducible Cf
