X-ray analysis , differential solution in inorganic acids , and optical spectroscopic analysis were used to study the genesis of the phase composition of Cu-Cr/Al2O3 catalysts for combustion of petroleum fuels. Interaction of the active components of these catalysts with their supports (γ-, (γ+χ)-, δ-, and α-Al2O3) depends on the nature of the Al2O3 and preparation conditions. For γ-Al2O3, this interaction starts already during catalyst calcination at 970 K, but α-Al2O3 interaction, with the formation of solid solution CuCr2-xAlxO4, occurs only after heating at 1270 K. This interaction substantially changes the phase composition of the support and results in a decrease in the temperature of polymorphic transformations of Al2O3. A complex character of the genesis of the phase composition of these catalysts makes it impossible to draw some clear conclusions at this stage of the study with regard to the nature of the active sites in oxidation reactions . The results obtained permit to predict the thermal stability of these catalysts in combustion of fuels.
