The results of a study of the activity of polyoxide catalysts based on molybdenum, chromium and gallium supported on natural clays for the catalytic oxidation of light alkanes to industrially important chemical products are presented. Studies of the oxidative conversion of a propane-butane mixture on molybdenum, chromium and gallium polyoxometallates supported on natural clays allowed to determine that the predominant composition of the products is determined by the temperature of the process. It was found that the production of a number of products with high yields: acetaldehyde - at 673-723 K, acetone - at 823 K, methanol - at 673-723 K, MEK - at 773-823 K, ethanol - at 823 K, ethylene - at 673 -723 K, H₂ - at 823 K is possible at oxidative conversion of propane-butane mixture at GHSV = 450 h^-1 on the developed three-component supported Mo-Cr-Ga catalysts.
