“…It should be noted that the phenomenon of the resonant effect of the intensity of mechanical activation, which includes cavitation, was observed for other technologies that employ mechanical methods for the selective energy supply to reaction centers. For example, a method known as "aerosol nanocatalysis" [15] implies the activation and formation of a constant concentration of the aerosol of hyperactive catalytic particles due to a change in the frequency of fluctuations of the catalytic system, consisting of a catalyst powder with initial dimensions up to 200 µm and a material that disperses this catalyst, whose dimensions are up to 1.2 mm. The study into various processes of hydrocarbon treatment involving this method revealed the presence of abnormal maximum dependences of the effective constant of cracking reaction rates at certain frequencies of fluctuations in the catalytic system, as well as a change in the yield of individual products.…”

“…As a result of the search, the choice focused on the new evolving technology of aerosol nanocatalysis. The technology has already proven successful in the processes of catalytic cracking of vacuum gasoil on zeolite catalysts [18]. In this regard, it should be noted that the complex physical and chemical characteristics of raw materials do not make it possible to use conventional catalytic systems in the process of fuel oil refining to a fraction of light hydrocarbons.…”

The primary oil processing product is a mixture of different hydrocarbons. One of the hard-to-process petroleum products is fuel oil. This paper considers a method to derive clear (light) fractions of petroleum products by the catalytic processing of fuel oil on a zeolite-containing catalyst at 1 atm under the technological conditions of aerosol nanocatalysis. The prospect of the catalytic processing of a viscous residue ‒ fuel oil ‒ has been analyzed and estimated. The process is carried out by dispersing the catalytically active component in a vibratory-fluidized layer. Chemical transformation occurs during the constant mechanochemical activation of catalyst particles by forming an aerosol cloud in the reactive volume. Natural zeolite catalyst of the type Y was selected for research. Methods for separating the gasoline and diesel fractions of light hydrocarbons and for analyzing the gas phase have been given. The effect of the concentration of zeolite catalyst aerosol on the composition of cracking products (the yield of the gasoline and diesel fractions of light hydrocarbons) has been studied. It is noted that the rate of the course of fuel oil processing in the aerosol of the catalyst is 1.5‒2 times higher than that in thermal processing. It has been found that in fuel oil processing based on the aerosol nanocatalysis technology, the concentration of the catalyst can be controlled to produce the final product. The study results have shown that the optimal conditions for processing fuel oil in the aerosol of the catalyst should be considered 773 K, a frequency of 5 Hz, a pressure of 1 atm. At the same time, a concentration of the catalyst of 1‒5 g/m3 should be considered optimal for the output of a light fraction of hydrocarbons. In this case, the yield is up to 80 % of the fraction in the laboratory. It was found out that during the processing of fuel oil, the concentration of the catalyst makes it possible to optimize the output of light oil products under the technological conditions of aerosol nanocatalysis

“…In this case, long-chain hydrocarbons in oil residue are broken down to simpler molecules as light hydrocarbons, by the breaking of carbon-carbon bonds at results of cracking process. As a result of the cracking process, this residue obtained a fuel fraction [14][15][16]. In addition, it has been shown that it is possible to increase the fuel fraction yield as a result of the cracking process of high paraffin oil residues in Mongolia.…”

Cracking is the complex physical and chemical process of converting high molecular hydrocarbons into valuable products such as gasoline fraction and light fuel fraction. There are several oil fields in Mongolia and three large deposits already are being exploited. The crude oil was classified as high-paraffinic crude oil because of its high viscosity and low yield of fuel fraction. The contents of asphaltenes and resins in the oil were low. Therefore, the cracking process is necessary to convert the paraffinic Mongolian crude oil to lighter distillates for the production of transportation fuels and chemicals. In this work, we studied the hydrocracking process of atmospheric residue (>350°C) to produce fuel fractions from high paraffin Tsagaan-Els oil of Mongolia. The hydrocracking experiment was carried out with and without a catalyst at temperature 450°C for 1-3 h under a hydrogen pressure of 5 MPa. Commercial Ni-Mo/Al2O3 catalyst (Ni 3%, Mo 15%) was used in the hydrocracking experiments for 1 and 2 h. The yields of light and middle distillates obtained by hydrocracking of the atmospheric residue for 3 h without catalyst were 15.8 and 17.7 wt.%, respectively. The effect of catalyst was tested in the experiments for 2 h. By the hydrocracking with catalyst, the yield of light distillate has increased 4.5 wt.% in comparison with the yield of light distillate obtained from the experiment without catalyst. In this study, we report that the atmospheric residue in the Tsagaan-Els oil could be liquefied by thermal cracking at 350°C to increase the yield of gasoline and diesel fuel.
