This study aimed to prepare catalysts on the base of Kazakhstan raw materials and test them in the oxidative catalytic cracking of fuel oils. It was determined the influence of air on the route of cracking reactions and establish the relationship between the parameters of oxidative catalytic cracking and the degree of conversion of high molecular weight hydrocarbons to light products. It was found that the air additives contribute to a deeper degradation of hydrocarbons of the starting material. According to the IR spectra, the oxidative cracking gasoline carried out without a catalyst contains sulfur compounds bound to the oxygen atom (927-1,007 cm-1) and carbon (747 cm-1). With an increase in the volumetric flow rate of air and processed feedstock, in the presence of a catalyst, sulfur-containing hydrocarbons are likely to be oxidized. The introduction of air additives into the reactor increases the fraction of the dehydrogenation reaction for lighter-boiling hydrocarbons (fraction 185-340°C) and does not affect the degree of dehydrogenation of the heavier fraction. The addition of air oxygen to the reactor when carrying out catalytic cracking on the developed catalysts makes it possible to deepen the processing of fuel oil and significantly reduce the content of sulfur-containing compounds. The presence of a catalyst promotes their destruction and removal from the gasoline fraction.
