The composition of fragments bound through sulphide and ether bridges in the molecules of initial resins and the liquid products of their conversion at 450 °C under the conditions of laboratory experiment was studied using a set of physicochemical methods (IR spectroscopy, UV spectroscopy, gas chromatography - mass spectrometry, chemical destruction). It is shown that the fragments undergoing destruction are mainly those bound in the structure of the initial sample through the least thermally stable functional groups of esters and aliphatic sulphides. Sulphur- and ether-bound compounds in the structure of both resin samples are represented by n-alkanes, n-alkylcyclopentanes, n-alkylcyclohexanes and hopanes. The presence of nickel porphyrins was established among the sulphur-bound compounds. It is the molecular composition of bound n-alkanes that changes most noticeably during thermolysis. Ether bond cleavage in the molecules of secondary resins leads to the formation of products containing mono- and dibromides of alkyl biphenyls. This fact provides evidence that these aromatic compounds are present in resins in the form of fragments bound with other structural fragments through one and two ether bridges.","PeriodicalId":44968,"journal":{"name":"Chemistry for Sustainable Development","volume":"8 9","pages":""},"PeriodicalIF":0.4,"publicationDate":"2024-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141343362","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Acyclic organic compounds have been identified: n-alkanes, fatty acids, n-alkane-2-ones, aldehydes, n-alkanols. The long-chain saturated alcohol 10-nonacosanol was found in the leaves of Sorbus aucuparia. Aliphatic diterpenoids phytone and the isomers of phytol, triterpene squalene, as well as naphthenoaromatic compounds vitamin E (tocopherol) and vitamin K1 (phytanodione) were detected among isoprenoid structures in the leaves of S. aucuparia, increased phytol and fatty acid levels are observed in the leaves of S. aucuparia 3 months and 1 year after the fire event, and then the concentrations of these compounds decrease to background values after 2 years. Squalene content in the leaves of S. aucuparia, which decreased as a result of the fire event, increased sharply the following year, and after 2 years, it still remained at a level significantly higher than the background. The fire had the greatest impact on the long-chain alcohol 10-nonacosanol, which was detected in large amounts in the leaves of S. aucuparia. As a result of the fire, there is a drop in its content to trace amounts, followed by a slight increase the following year and an abrupt increase up to background values after 2 years. During the two-year-long post-pyrogenic restoration, changes in the molecular mass distribution of acyclic compounds are observed. The leaves of S. aucuparia, sampled 3 months and the following year after the fire, exhibited a shift from higher molecular homologues to less higher molecular n-alkanes and n-aldehydes in comparison with the leaves from background sites, while the corresponding shift observed in C. arborescens related to n-alkane-2-ones.

The amounts of pollutants entering the atmosphere from associated petroleum gas combustion were calculated: carbon monoxide (CO) - 83 %, nitrogen dioxide (NO2) - 0.7 %, soot - 10 %, methane - 6 %. The vegetation cover was mapped relying on the Sentinel-2 satellite image with the shooting date of June 14, 2021, displaying dispersion fields for СО, NO2 and soot. The distances from emission source (flare installation) to isolines with CO and soot concentrations equal to 1 MPCst (5 and 0.15 mg/m3) are 163 and 505 m, respectively (here MPCst is the maximum permissible concentration for short-term exposure level). Similarly, measured distance to the isoline with NO2 concentration 0.1 MPCst concentration (0.02 mg/m3) is 284 m. On average, CO concentration decreases by 1 mg/m3 at a distance of 86 m and becomes equal to 0.2 mg/m3 (0.04 MPCst) at a distance of about 572 m. The resulting model for CO dispersion does not contradict MERRA-2 satellite data, according to which the concentration of CO in the vicinity of the flare installation was 0.2 mg/m3. The gas chromatographic - mass spectrometric analysis of soil samples and plants collected to the north-east from the flare installation at a distance of 216, 486, 710, 1037 and 1380 m has shown that aliphatic hydrocarbons prevail in the composition of soil organic matter. Their content varies from 50 to 80 % of all identified compounds, with the predominance of high-molecular homologues (C27-C33). The maximum total amount of n-alkanes (75.3 μg/g) was detected in the soil sample taken at a distance of 710 m from the flare installation. In the organic matter of pine needles and blueberry leaves, C27 homologue dominates, and C25, C29, C31 characteristic of terrestrial vegetation are present. In addition, polyaromatic compounds were identified in the soil: anthracene/phenanthrene, fluoranthene and pyrene.","PeriodicalId":44968,"journal":{"name":"Chemistry for Sustainable Development","volume":"28 12","pages":""},"PeriodicalIF":0.4,"publicationDate":"2024-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141338927","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effect of this composition on oil recovery enhancement is studied, and results obtained in the laboratory studies of the effect of DES-based composition on the filtration characteristics of a heterogeneous formation in the carbonate reservoir of the Usinsk field are presented. The efficiency of the composition for oilfields at the early and late stages of development has been assessed by physical modelling. The treatment of a model of a heterogeneous reservoir with the composition is determined to cause a substantial increase in oil displacement coefficient at either low or high temperatures due to equalisation of filtration flows, an increase in reservoir coverage, and restoration of initial permeability. Investigation of the composition and properties of heavy high-viscosity oil before and after treatment with the composition shows that the application of DES-based acid composition does not affect the qualitative composition of oil. The use of the composition leads mainly to redistribution of the content of low- and high-molecular structures: predominantly light occluded hydrocarbons are displaced, while heavy oil components are adsorbed on the reservoir.","PeriodicalId":44968,"journal":{"name":"Chemistry for Sustainable Development","volume":"26 24","pages":""},"PeriodicalIF":0.4,"publicationDate":"2024-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141342698","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The digital maps of the arrangement of hydrocarbon fields in the Bazhenov, Domanik and Kuonamka sediments over the territories of the Volga-Ural, Timan-Pechora and Lena-Tunguska oil and gas bearing basins are presented. The distribution of oils from these deposits over the depth of occurrence in each basin is shown. The lithological features of reservoir rocks are established. The average values of reservoir parameters characterising the filtration and capacitance properties of the pools in these sediments are determined. To analyse the conditions of Bazhenov oil occurrence, a batch of 2833 oil samples from 127 fields of the West Siberian basin was used, for Domanik oil - 407 samples from 195 fields of the Volga-Ural and Timan-Pechora basins, and for Kuonamka oil - 117 samples from 28 fields of the Lena-Tunguska basin. A comparative analysis of the geological and physical characteristics producing a direct impact on the development regime and the effectiveness of technologies used to extract these hard-to-recover oils was carried out: permeability and porosity of rocks, reservoir temperature and pressure. It is shown that the Domanik and Kuonamka sediments are the closest in characteristics to the reservoirs of the developed American shale oil fields, which indicates the possibility for effective application of the positive experience of the United States for Russian oilfields. The results of the study can be used in the development of new and improvement of existing methods and technologies for the extraction and processing of hard-to-recover oils from the studied sediments.","PeriodicalId":44968,"journal":{"name":"Chemistry for Sustainable Development","volume":"8 6","pages":""},"PeriodicalIF":0.4,"publicationDate":"2024-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141339113","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Quantitative measurements show that hydrogen sulphide is present in the water and bottom sediments of most of the lakes studied. In addition to hydrogen sulphide, the presence of sulphate, thiosulphate, and elemental sulphur was detected in the water column, while sulphate and elemental sulphur were found in the bottom sediments. It was established that elemental sulphur exists in the lakes primarily in the form of suspension and colloids, as well as polysulphidic sulphur, the amount of which increases with increasing water pH. It is concluded from the isotopic ratios of sulphur for sulphate, hydrosulphide ions, and elemental sulphur that sulphur in the studied natural systems is controlled by biological and geochemical processes. One of the processes controlling the behaviour of sulphate ions in the lakes is sulphate reduction, which leads to the enrichment of sulphate sulphur and depletion of sulphur in hydrogen sulphide with the 34S isotope. It is shown that oxidation of reduced sulphur in the lakes proceeds with the participation of oxygen, iron, manganese, as well as various bacteria. The presence of an additional source of sulphur and/or absence of sulphur reduction causes 32S accumulation in sulphate ions. It is determined that the loss of sulphate ions due to their bacterial reduction in bottom sediments is most pronounced in the chloride and soda lakes of the I and III subtypes. In the sulphate and soda lakes of the II subtype, an increase in the amount of sulphate ions was detected.","PeriodicalId":44968,"journal":{"name":"Chemistry for Sustainable Development","volume":"39 19","pages":""},"PeriodicalIF":0.4,"publicationDate":"2024-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141344380","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
