The characteristics of the catalysts of ozonolytic treatment of aromatic hydrocarbons were studied using physicochemical analysis methods (XPA, BET, TGA, SEM). The catalytic system Mg-Cr was determined to be the most efficient one in the reaction of ozonolytic desulphurization of hydrocarbons. It was established that carbon fragments are accumulated on the catalyst surface during ozonolytic desulphurization of the benzene fraction, which is connected with the adsorption of sulphur-containing molecules and with the oxidation of condensed hydrocarbon fragments of the raw material.
