One such pyrolysis oil is shale oil obtained by pyrolysis of kukersite oil shale. K shale oil consists mainly of aromatic structures with straight alkyl side chains. For samples with comparable boiling point distributions, kukersite shale oil is more aromatic than petroleum and many other shale oils. Sulfur, nitrogen, and oxygen are often incorporated into the ring structures, with much of the oxygen also present as phenolic hydroxyl groups.To evaluate the potential for producing some specific compounds from kukersite shale oil foundational data on the composition is needed. Here we analyze new data on the elemental composition and infrared spectrum of kukersite shale oil to investigate its composition. To get detailed information on how the composition of the oil changes depending on the average molecular weight of the oil fraction, the shale oil was separated into narrow boiling fractions using distillation.The results show that the nitrogen content in kukersite shale oil increases with the boiling temperature, with the heaviest fractions containing about 0.3 wt%. Sulfur content reaches a maximum of almost 2 wt% for fractions boiling between 150 and 190 °C, and heavier fractions contain about 0.7 wt%. Similarly, the proportion of hydroxyl groups in kukersite shale oil peaks in the fraction boiling at about 320 °C, with heavier fractions containing more aromatic and alkyl functional groups. The elemental composition of kukersite shale oil is also compared to that of other shale oils.","PeriodicalId":19441,"journal":{"name":"Oil Shale","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2022-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76353767","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}

This article investigates a potential for using models based on infrared spectra to predict basic thermodynamic properties of narrow boiling range oil fractions or pseudocomponents. The work took advantage of the simultaneous availability of a property database of narrow boiling range fractions of Kukersite oil shale retort oil (from the industrial retorting process) together with infrared spectra of these fractions. The work was based on the hypothesis that the models based on infrared spectra could potentially be used to reduce experimental data when developing other predictive methods, or even as a substitute for other prediction methods. In this study four basic oil properties, which are often used to predict other thermodynamic properties, were predicted from infrared spectra using support vector regression. These were specific gravity, refractive index parameter, average boiling point and molecular weight. According to bulk property prediction approach these selected properties can be grouped into energy parameters (two former) and size parameters (two latter). It was found that, for distillation fractions with varying compositions, both the energy parameters (specific gravity, refractive index) as well as the size parameters (molecular weight, average boiling point) can be predicted from Fourier transform infrared (FTIR) spectra, and that the accuracy of the predictions based on infrared spectra was comparable with the accuracies of petroleum bulk property correlations. Thus, infrared spectra can provide a convenient alternative in the thermodynamic property prediction field because they can be easily measured and correlated to a wide variety of properties.","PeriodicalId":19441,"journal":{"name":"Oil Shale","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84107571","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}
