Experiment planning is the optimal control of an experiment in the context of incomplete information about the process mechanism. Interest in the science of experiment is associated with a wide range of experimental studies and a significant economic effect from the optimal organization of the experiment. An optimal experiment is a way to save time and cash, increase reliability of results. Middle fraction of Kumkol oil (200-300 degrees C) was used to study the cavitation effect on fuel oil. The following catalytic systems were used, namely, modified FeS2, nanocatalysts epsilon-Fe2O3/SiO2, alpha-Fe2O3/SiO2 spherical catalyst, beta-FeOOH, and Fe(OA)(3). By quantifying the individual composition of the middle fraction (200-300 degrees C) of Kumkol oil, a general pattern of the effect of catalytic-cavitation processing on the hydrocarbon composition of the middle fraction (200-300 degrees C) of Kumkol oil was established. The optimal conditions and a number of factors affecting the cavitation processing of the middle oil fraction (200-300 degrees C) in the presence of a FeS2 catalyst were determined. In accordance with the regression equation obtained, the optimal conditions for cavitation processing are the following: tau = 90-120 s, the amount of added catalyst is 0.7-1 g and the amount of added water is 1.5-2 ml.

The results of a study on the hydrogenation of a mixture of anthracene and phenanthrene in the presence of nanocatalysts (Fe 3 O 4 and β-FeOOH) and catalytic additives (microspheres obtained from the ash of coals from the Republic of Kazakhstan and nickel and cobalt additives supported on the microspheres) are presented. The efficiency of a wet mixing method for the preparation of nickel and cobalt oxide catalytic additives on the microspheres in the process of the hydrogenation of a mixture of anthracene and phenanthrene was shown. The hydrogenation process of a mixture of polyaromatic hydrocarbons was represented as a combination of hydrogenation and destruction reactions. The individual chemical composition of the hydrogenation products of a mixture of anthracene and phenanthrene was investigated. The activity and selectivity of the catalysts and catalytic additives in the hydrogenation process of a mixture of polyaromatic hydrocarbons were established.

One of the priority directions in the Republic of Kazakhstan is the production of low-sulfur coke with sulfur content up to 1 % and needle coke used in the electrode industry, which is fully purchased by import. Needle coke is used to produce high-quality graphite electrodes needed for the steel industry. Electrodes should have high mechanical strength, electrical conductivity, and low sulfur content. The primary raw material for obtaining diesel fuel and needle coke is the primary coal tar produced at ShubarkolKomir JSC. At present, the obtained products are not processed into valuable chemical substances and motor fuels on the territory of the Republic of Kazakhstan. The physicochemical properties of trademarks 0–10, 10–25, 25–40, 0–60, 10–60, 0–25 mm produced at ShubarkolKomir JSC have been investigated: coke properties by particle size classes — elemental composition of organic part and ash residue, coke ash, specific and apparent density of the samples, porosity of coke samples with subdivision into macro-, mesoand micropores. The chemical composition of coke is determined by technical analysis (moisture, ash content, sulfur content, phosphorus content, volatile matter yield) and elemental analysis (carbon, hydrogen, oxygen, nitrogen, etc.) content.
