Rational use of associated petroleum gas is one of the priorities facing the oil and gas complex of the Republic of Kazakhstan. The obtained results on the conversion of a propane-butane mixture on synthesized polyoxide catalysts can serve as the basis for the development and creation of a technology for processing associated petroleum gas components into hydrocarbons of greater chemical significance, namely aromatic compounds. The composition of the catalytic system, the process conditions have been optimized, it allows to obtain the maximum possible amount of the target product from gaseous hydrocarbons. The industrial implementation of this process will make it possible to rationally use associated petroleum gas, which will expand the raw material capabilities of the petrochemical sector. The process of oxidation of a propane-butane mixture in a catalytic system deposited on a natural support has been studied. Torgai white clay was chosen as a natural support. The effects of temperature, volumetric rate, composition of the active phase, the ratio of initial reaction mixtures on the reaction of partial oxidation were determined. Among the studied catalysts, MoCrGa with an active phase content of 1 % showed high activity in terms of the yield of reaction products of the partial oxidation of the propane-butane mixture, while the yield of benzene reached 83 %. The properties of the 1 % MoCrGa catalyst deposited on Torgai white clay were studied by XRPA, EM methods. According to the results of XRPA, there is a similarity in the structure of the 1 % MoCrGa/TWC catalyst and Torgai white clay. Since the catalysts are X-ray amorphous, they were studied by electron microscopy. The size of the catalyst was 10–20 nm; the phase composition of the resulting catalysts was also determined at temperatures of 723K, 823K; the activity of the 1% MoCrGa/TWC catalyst was directly related to the phase composition
