Abstract. Optimization of the hardware design and technological modes of the typical steam column in the hydrotreating unit of the CCR catalytic reforming unit has been performed. To achieve clear separation of fractions corresponding to their potential content in unstable hydrogenate, an instrumentation design for a complex column with side draws and a stripping section is proposed, which minimizes the content of C2-C4 and C7+ hydrocarbons in the light gasoline fraction while also enabling the isolation of an additional 70-95°C fraction.

Abstract. The influence of process mode parameters on the characteristics of the resulting greases with thickeners based on three types of detergent additives is considered: sulfonates, alkyl salicylates and alkyl phenolates of calcium. It is noted that each of the specified components has its own optimal conditions for greases production properties, which is due to the peculiarities of their chemical composition and structure. One of the key stages is structure formation, as well as the removal of excess water from the lubricant by heat treatment, the residual content of which can worsen the performance properties of the finished product and its stability.

Abstract. Currently, the effect of physical fields, in particular microwave radiation, on the processes of chemical transformations of inorganic and organic materials has become one of the promising methods for increasing their speed and selectivity of formation of target products. Due to the specialty of microwave heating, the use of electromagnetic energy of this given wave range opens up wide possibilities for the synthesis of effective catalytic systems intended for the potential implementation of oxidation-reduction and acid-base processes in oil refining and petrochemistry stimulating by an ultra-high-frequency electromagnetic field. This article presents the study results of the effect of microwave thermal action on the synthesis of activelyabsorptive microwave radiation, finely dispersed aluminum powder-reinforced aluminosilicate matrices characterized as [Al(x)Si(y)O(z)]X-, by combining hydro-thermal treatment of hydrogels precipitated from aluminum sulfate and sodium silicate solutions with their subsequent thermal treatment in a microwave field as potential catalysts for acid-base reactions. The achieving results presented in the article were supported through a detailed study of the variation dynamics of the generator power of microwave radiation (magnetron) and the exposure time of samples to form their phase composition and textural characteristics. It was found that an increase in the temperature and time of hydrothermal synthesis of the aluminum-reinforced aluminosilicate matrix and subsequent microwave treatment of the samples leads to an increase in the content of the crystalline phase of aluminum oxide in the amorphous aluminosilicate. It is shown that the amount of the crystalline phase of aluminum oxide in the amorphous aluminosilicate is not less than 10% by weight, relative to the total weight of the aluminosilicate composition. The presented textural characteristics of the samples allow us to recommend the synthesized composites for use as potential carriers and catalysts for oil refining and petrochemical processes stimulated by an ultra-high frequency electromagnetic field (2.45 GHz).

Abstract. The last 20 years have seen a significant increase in plastics production. The process of sorting solid municipal waste is very difficult and unsystematic, which complicates the recycling of plastics. Thermolysis is one of the most promising chemical methods for recycling plastic waste, since it allows you to obtain various types of fuel. Thermolysis products can be divided into three categories: gas product, liquid product (oil) and solid residue. Solid residues are very attractive raw materials for the production of various adsorbents, activated carbon or carbon nanotubes, or can be used as solid fuel. In this paper, we study solid carbon residues (CR) obtained because of the production of thermolysis oil by varying the composition of the gas mixture supplied to the reactor: 100% nitrogen or 80% nitrogen +20% air. The results of the HRTEM study of the samples showed that the obtained carbonized residues have a graphite-like structure and contain an admixture of calcium, which can be introduced during plastic production in the form of carbonate or stearate used as a pigment and stabilizer, respectively. According to nitrogen porosimetry, the specific surface area was 0.8-1.1 m2/g. Calcination of the obtained carbon residues at 400-500°C made it possible to significantly increase the specific surface area. According to the data obtained, after calcination, an increase in the specific surface area and total pore volume was observed in all cases, while all calcined samples were characterized by close values of the average pore size — 1.7-2.6 nm. For sample CR-1, during calcination at 500°C, it was possible to achieve an increase in the specific surface area by ∼130 times. While the specific surface area of sample CR-2, calcined at 500°C, increased by ∼57 times. Such improvement of textural properties by heat treatment opens up prospects for possible use of carbon residues obtained by thermolysis of plastics as additives for the production of automobile tires along with the use of commercial grades of technical carbon. The method of thermal analysis showed that the differential thermal analysis curve for a sample of carbonized residue obtained by thermolysis of a mixture of plastics in a flow of a mixture of air and nitrogen is similar to the data for petroleum coke, which indicates the possibility of using this material in pyrometallurgical processes.

Abstract. Abstract. Biofuels are environmentally friendly alternatives to petroleum fuels, containing vegetable oil and fatty acid esters. Biofuels are widely used in various industries in developed countries and are gradually being adopted worldwide. For Russia, the addition of fatty acid esters to petroleum fuels represents a new step in the biofuel sector’s development strategy. Therefore, it is important to understand the qualitative and quantitative results that blending fatty acid esters with domestic fuels can yield. In this study, engine tests were conducted on domestic diesel fuel and a biodiesel blend containing fatty acid esters obtained at the Empress Catherine II St. Petersburg Mining University. The results of the experiment showed that adding 5% ethyl fatty acid esters (FAEE) to diesel fuel reduced the average natural luminous flux attenuation index by half and increased its lubricity by 2.3 times
Keywords: biofuel, waste oil, biodiesel, fatty acid esters, smoke, environmentally friendly fuel, natural indicator of light flux attenuation

Abstract. The relevance of the development is due to the growth in the volume of oil products entering water bodies during accidental spills and leaks, which causes serious damage to ecosystems and human health. The paper proposes and reviews a new design of a belt installation for cleaning water surfaces from oil pollution. A review of existing oil collection methods (oil booms, skimmers, sorbents) was conducted and their main disadvantages were identified: High mobility and speed of deployment make the author’s new installation an effective tool for both emergency spill response and scheduled cleaning of water bodies. Application prospects include integration into emergency rescue services, use at industrial facilities and in remote areas. The resulting solution is a significant step forward in the field of environmental protection of water surfaces from oil pollution.
