Oxidative conversion of C3-C4 hydrocarbons by air to oxygen-containing compounds at T = 400-
550°C and space velocity of 7500 h-1, 9000h-1 on monoxide catalysts containing 1-, 3-, 5% Сo supported on natural
red clays was studied. The reaction temperature, contact time, change in the space velocity in the process of partial
oxidation of C3-C4 hydrocarbons have been studied.
Acid treatment of the sorbents contributed to the development of the surface area and the enlargement of pore
radius, which led to an increase of oxygen-containing compounds in the final product. The SiO2/Al2O3 ratio (silica
modulus) was increased after acid treatment too
