Modeling of catalytic-cavitation processing of middle oil fraction (200-300 ºС)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 FeS 2 , nanocatalysts ε-Fe 2 O 3 /SiO 2 , α-Fe 2 O 3 /SiO 2 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 FeS 2 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.
