According to the calculated EASY %Ro and Rock-Eval pyrolysis data, the highest maturity level of the organic matter reached by the hydrothermal treatment corresponded to the MC4 stage. As the hydrothermal treatment temperature of the oil shale was elevated up to 325°C, the dry pyrolysis of residual kerogen led to the predominant generation of wet gases in which C2+ prevailed over methane; at temperatures above 325°C, methane was predominant. Based on the pattern of the generation curves plotted individually for C1, C2, C3, C2–C5, and C4–C5 gases, methane was found to have additional sources in the kerogen structure, compared to C2+ gases. Ethane and ethylene are generated simultaneously via the free-radical decomposition of alkyl structures; moreover, at high pyrolysis temperatures, ethane and ethylene have some precursors other than those of C3+ gases.","PeriodicalId":725,"journal":{"name":"Petroleum Chemistry","volume":"64 6","pages":"688 - 696"},"PeriodicalIF":1.3,"publicationDate":"2024-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142186409","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ANN model was designed using 252 experimental data points taken from the literature. The properties of the distillates, namely, specific gravity and distillation temperatures, were the input parameters of the model. The training of the network was carried out using the Levenberg– Marquardt backpropagation algorithm and the early stopping technique. A comparison of the statistical parameters of different networks made it possible to determine the optimal number of neurons in the hidden layer with the best weight and bias values. The network containing nine hidden neurons was selected as the best predictive model. The ANN model as well as the Alqaheem–Riazi’s model was evaluated for the prediction of flash points by a statistical analysis based on the calculation of the mean square error, Pearson correlation coefficient, coefficient of determination, absolute percentage errors, and the mean absolute percentage error. The ANN model provided higher prediction accuracy over a wide distillation range than the Alqaheem–Riazi’s model. The developed ANN model is a reliable and fast tool for the low-cost estimation of flash points of petroleum middle distillates.","PeriodicalId":725,"journal":{"name":"Petroleum Chemistry","volume":"64 6","pages":"648 - 656"},"PeriodicalIF":1.3,"publicationDate":"2024-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142186410","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As compared to the extraction from the untreated rock, the hydrothermal treatment at 300°С in a СО2 medium allows recovery of a 6 times larger amount of the extract in the first step (in 20 h). In the second extraction step (68 h), the extract yield decreases by a factor of 8, but the relative content of saturated hydrocarbons in the extract increases by a factor of more than 3 compared to the first step, whereas the relative content of asphaltenes, resins, and aromatic compounds decreases. In the third extraction step (116 h), the extract yield is as low as 0.16%, the content of resins in it drastically decreases, whereas the content of asphaltenes increases to 52%. The extract of the fourth step (220 h) consists to 80.77% of asphaltenes. From the initial rock, the maximal yield of the extract enriched in saturated hydrocarbons with the minimal content of asphaltenes was observed after the second extraction step. In the course of prolonged extraction, the yield of petroleum fractions from the initial rock increases by a factor of almost 4, and in combination with the preliminary hydrothermal treatment, by a factor of 7. This fact demonstrates the possibility of generating an additional amount of hydrocarbons. Changes were revealed in the structural-group, hydrocarbon, elemental, and microelemental composition of petroleum fractions recovered from the low-permeability Domanik rock, depending on the extraction time and transformations of the organic matter of this rock in the course of hydrothermal treatment.","PeriodicalId":725,"journal":{"name":"Petroleum Chemistry","volume":"64 5","pages":"557 - 569"},"PeriodicalIF":1.3,"publicationDate":"2024-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141884498","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For this purpose, a new and efficient synthetic composite mesoporous nano-catalyst has been designed by enhancing morphological and mechanical properties of gamma alumina (γ-Al2O3) on a carbon nano fiber (CNF) as multiple supports. Four different catalysts based on different amount of CNF have been designed. X-Ray diffraction (XRD), X-Ray fluorescence (XRF), crash strength test, thermal gravimetric examination (TGA), and surface area (BET) have been used to characterize the catalysts. The catalyst with 10% loading of CNF (CAT-3) has been found to increase the tensile strength by more than 200% compared to the CNF-free sample (CAT-4). Then, a series of experiments has been conducted in a batch ODS reactor with air as an oxidant and light gas oil (LGO) as a real feedstock to evaluate the effectiveness of the designed catalysts and the performance of the reactor. The new catalyst has been clearly shown to be a significant factor in sulfur removal resulting in a clean fuel.","PeriodicalId":725,"journal":{"name":"Petroleum Chemistry","volume":"64 4","pages":"458 - 470"},"PeriodicalIF":1.3,"publicationDate":"2024-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141884499","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this study was to investigate the molecular structure of asphaltenes in order to shed light on the causes of their precipitation. To this end, the molecular structures of stable (remaining in the solution) and unstable (precipitated) asphaltenes were characterized by EPR, NMR, and IR spectroscopy. Using crude oil asphaltenes and air-blown asphalt as objects for the study, only weak increasing and decreasing trends were observed in the content of aromatics and oxygenates, respectively, in the unstable asphaltene fraction. The stable and unstable asphaltenes were found to differ in adsorption capacity. It was shown that the species adsorbed on asphaltenes are rich in moieties of aromatic acid esters, and that removing these species further eliminates the structural-group composition differences between stable and unstable asphaltenes. The study findings suggest that the stability of asphaltenes in crude oils can be controlled by introducing synthetic aromatic acid esters structurally similar to natural surfactants.","PeriodicalId":725,"journal":{"name":"Petroleum Chemistry","volume":"64 5","pages":"570 - 579"},"PeriodicalIF":1.3,"publicationDate":"2024-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141567378","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The potential of the carbonate rock is utilized virtually completely in SBW at 320°С. From the high-carbon Domanik rock, SBW allows only more complete extraction of free hydrocarbons, asphaltene compounds, and solid n-alkanes without significantly altering the kerogen structures. The kerogen degradation occurs most intensely in SCW and is accompanied by a decrease in the generation potential and by an increase productive capacity of the rock. In the oil extracted from the high-carbon rock with SCW at 374°С, the content of saturated and aromatic fractions increases by a factor of more than 2, the content of asphaltenes and resins decreases, and carbenes/carboids are formed. At 420°С, the oil yield and the content of carbenes/carboids decrease. In the extraction from the carbonate rock, on the contrary, at 374°С the content of light oil fractions decreases, and the fraction of resins increases by a factor of more than 1.5; at 420°С, the content of asphaltenes increases by a factor of more than 2.
