“…The data of the TEM and XPA studies (Figure 6) show that the catalysts proposed in the work are highly dispersed, and the metals of the active phase are mainly in an oxidized state. There are associated clusters on the surface, and their characteristics, such as dispersion, structure, are determined by the nature of the catalyst components [11,20,38]. According to the results of IR spectroscopy (Figure 7), all samples are characterized by the presence of peaks at 1050 and 780 cm-1, which are responsible for the stretching and bending of the Si-O-Si bond (asymmetric and symmetric stretching vibration of Si-O-Si), respectively, 1215 cm -1 is the peak corresponding to the bond Si-O-H [43][44][45][46][47].…”

“…However, it becomes more difficult to process such heavy hydrocarbons on traditional catalysts. In the oil refining industry, deep hydrotreating and hydroisomerization of oil fractions are increasingly used to produce high-quality motor fuels [9][10][11][12][13][14][15][16]. Oil produced in the oil fields of the Republic of Kazakhstan is characterized by a high content of sulfur.…”

The oil produced in the oil fields of the Republic of Kazakhstan contains a high percentage of sulfur. Synthesis and improvement of the properties of catalytic systems for the production of fuels with high octane number and low sulfur content is currently an urgent task for Kazakhstan. In this study, catalytic systems with a new composition based on zeolites with the addition of rare-earth metals (E) and phosphorus (P) have been prepared and tested in the process of the catalytic hydrotreating of straight-run gasoline and gasoline of catalytic cracking. In case of NiO-MoO3-E-P-HZSM-HY-Al2O3 catalyst, the octane rating of the gasoline after hydro-processing was increased to 88-90, which is much higher than for other catalysts. The octane number of straight-run gasoline up to 400°C is a maximum of 90 (Research Method) and 83.7 (Motor Method). At the same time, the sulfur content in the resulting gasoline decreases from 0.0088% to 0.0011%. In the case of catalytic cracking gasoline, the sulfur content is reduced from 0.0134% to 0.0012%. The smallest residual sulfur content in the final product, 0.0005% is revealed in case of catalyst CoO-WO3-E-P-HZSM-HY-Al2O3, and it is 2-4 times lower than for catalysts CoO-MoO3-E-P-HZSM-HY-Al2O3 and NiO-MoO3-E-P-HZSM-HY-Al2O3. These amounts of sulfur residue in raw materials is lower than that required by the Euro-5 Standard. The surface of the prepared catalysts was 211.0-274.0 m2/g, diameter of pores d ≈ 1.5-2.5 nm and d ≈ 7.0 nm. The total pore volume of the catalysts was not higher than 0.28-0.41 ml/g. The catalysts developed in this study can be used for hydrotreating raw materials and producing high-octane gasoline with a low sulfur content, corresponding in its characteristics to the Euro-5 Standard.

“…Most scientists in the field recognize that the specific properties and complex composition of heavy oils and oil residues do not allow the use of classical processing methods for light oils; such schemes are ineffective or not suitable at all [1,2,4,[14][15][16]. One of the actual methods of intensification of thermal processes of refining of high-viscosity oils is wave action (ultrasonic, acoustic, ultra-frequency) [56][57][58][59][60][61][62][63][64][65].…”

“…These results, obtained by various authors, indicate the feasibility of processing heavy oil fractions by oxidative cracking. An analysis of the data of various scientific schools allows us to conclude that one of the most promising ways to increase the depth of processing of heavy oil fractions is to carry out catalytic cracking in an oxidizing medium, for example, with controlled air supply to the reactor [58][59][60][61][62][63][64][65][66][67][68][69][70][71][72][73][74][75].…”

Catalytic cracking of M-100 fuel oil: relationships between origin process parameters and conversion products

et al. 2022

The development of technologies for processing oil residues is relevant and promising for Kazakhstan, since the main oil reserves of hydrocarbons in the country are in heavy oils. This paper describes the study of the influence of technological modes on the yield and hydrocarbon composition of products formed because of cracking of commercial fuel oil and fuel oil M-100 in the presence of air in the reactor. For catalysts preparation, natural Taizhuzgen zeolite and Narynkol clay were used. It was found that the introduction of air into the reaction zone, in which oxygen is the initiator of the cracking process, significantly increases the yield of the middle distillate fractions. In the presence of air, the yield of diene and cyclodiene hydrocarbons significantly increases compared to cracking in an inert atmosphere. According to the data of IR spectral analysis of M-100 grade oil fractions, in addition to normal alkanes, the final sample contains a significant amount of olefinic and aromatic hydrocarbons. On the optimal catalyst, owing to oxidative cracking of fuel oil, the following product compositions (in %) were established: Fuel oil M-100: gas – 0.8, gasoline – 1.1, light gas oil – 85.7, heavy residue – 11.9, loss – 0.5 and total – 100.0%; commodity Fuel oil (M-100): gas – 3.3, gasoline – 8.4, light gas oil – 84.3, heavy residue – 4.0, loss – 0 and total – 100.0%.

The paper describes the catalytic cracking of heavy petroleum feedstock on catalysts based natural Taizhuzgen zeolite and Narynkol clay (Kazakhstan). Catalytic cracking was studied on fuel oil of the M-100 brand taken from the LLP Pavlodar Oil Chemistry Refinery (Kazakhstan). Air was added into the reaction medium. It was found that under optimal conditions, the conversion of the heavy residue of M-100 fuel oil reaches 46.2%, when cracking the initial fuel oil, the yield of the middle distillate fraction is 85.7 wt. % due to the content of 41.1 wt. % residual light gas oil in the resulting products. The optimal composite catalyst allows carry out the cracking of heavy oil residues without preliminary purification and with a high degree ofconversion to diesel fraction.
