This work presents the results of the process of thermolysis of straight- run fuel oil of the Pavlodar Oil Refinery using the Kendyrlyk shale and zeolite of the Semey-tau deposit as an activating additive. By spectral analysis has been shown that there is a significant amount of elements which manifest catalytic properties (Mo = 6·10-4 %, Ni = 2·10-3 %, Ti = 1.8·10-1 %, Zn = 50·10-3 %) in zeolite treated at 400 °C. The thermally treated zeolite was examined using thermogravimetric (DGA) and infrared spectroscopic analysis methods. It has been demonstrated that, the increase concentration of zeolite in the system from 1 to 5%, the yield of light petroleum products in the fractions increase and reache the values obtained in the use of combustible shale. Based obtained data the effect of zeolites on the process of thermolysis of HOR (heavy oil residues), it can be said that the reaction of catalytic cracking of molecules of heavy materials occurs via the carbonium-ion mechanism both in the presence of an organo-mineral activator and of zeolite.
