Description
Summary:	Improving the efficiency of processing heavy oil residues into light petroleum products and raw materials is an urgent task for Kazakhstan and other countries that produce and consume petroleum products. Really the share of heavy oil and natural bitumen in the balance of hydrocarbon raw materials produced will continuously increase. The aim of the study was preparation of catalysts based on Taizhuzgen zeolite and Narynkol clay (Kazakhstan) and determination their efficiency in the process of oxidative cracking of vacuum distillates of Atyrau and Zhetybai oil. The IR spectra of the obtained gasolines indicate that the reactions of incomplete oxidation of hydrocarbons in the course of oxidative cracking practically do not occur. At low volume feed rates of the initial substance to the reactor, the yield of diene and cyclodiene hydrocarbons in the presence of air additives significantly increases in comparison with cracking carried out without air additives to the reactor. The direction of the oxidative cracking process changes with an increase in the volume rate of the suspension feed. Obviously that the air of definite concentrations in the reactor contribute to a deeper destruction of the hydrocarbons of the vacuum gas oils investigated.
