The physicochemical properties of Cr2O3/- Al2O3 catalysts obtained by heat treatment of the sample (precursor) in nitrogen and air between 110 and 600°C and their influence on the catalytic activity in tetrachloroethylene hydrofluorination was studied by the TA, TPD, X-ray diffraction, BET, and DRS methods. It was shown that the temperature and gas composition of precursor pretreatment strong effect on the specific surface area and activity of the catalysts. The CrO1.9 compounds are more active than CrO1.5. For more active catalyst sample kinetic study was performed.
