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 oC) was used to study the cavitation effect on fuel oil. The following catalytic systems were used, namely, modified FeS2, nanocatalysts ε-Fe2O3/SiO2, α-Fe2O3/SiO2 spherical catalyst, β-FeOOH, and Fe(OA)3. By quantifying the individual composition of the middle fraction (200–300 oС) of Kumkol oil, a general pattern of the effect of catalytic-cavitation processing on the hydrocarbon composition of the middle fraction (200– 300 oС) of Kumkol oil was established. The optimal conditions and a number of factors affecting the cavitation processing of the middle oil fraction (200–300 oС) 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: τ = 90–120 s, the amount of added catalyst is 0.7–1 g and the amount of added water is 1.5–2 ml.
