Постоянный рост органополимерных отходов, в частности автомобильных шин, стимулировал поиск способов их переработки. Известно, что перспективным методом их переработки является пиролиз в различных режимах [<xref ref-type="bibr" rid="cit1">1</xref>]. Комплексное изучение состава и свойств образующихся пиролизных масел, полученных из отработанных шин, позволит выяснить возможность их использования в качестве вторичного сырья для производства углеводородных топлив. В работе с использованием метода экстракционной пробоподготовки определен компонентный состав тяжелой парафинистой нефти Речицкого месторождения и пиролизного масла, полученного при термической обработке резинотехнических изделий в среде азота, методами ИК-спектроскопии, элементного и ГХ-МС анализа. Кроме того, определены их фракционный состав, плотности фракций, а также йодное число. На основании полученных результатов сделаны выводы о схожести и различиях пиролизного масла с нефтью. Высказано предположение, что жидкие продукты пиролиза после соответствующей обработки могут быть использованы в качестве добавок к нефтепродуктам, что способствует решению проблем не только как утилизации отработанных шин, так и истощения легкодоступных запасов нефти.</p></abstract><trans-abstract xml:lang="en"><p>The problem of alternative sources of hydrocarbon fuels is currently of great importance. The constant growth of organopolymer waste, in particular, automobile tires, has stimulated the search for ways to recycle them. It was found that a promising method of their processing is pyrolysis in various modes [<xref ref-type="bibr" rid="cit1">1</xref>]. A comprehensive study of the composition and properties of the resulting pyrolysis oils obtained from used tires will make it possible to find out the possibility of their use as a secondary raw material for the production of hydrocarbon fuels. In this work, the component composition of heavy paraffinic oil from the Rechitsa field and pyrolysis oil obtained during the thermal treatment of rubber products in a nitrogen atmosphere, by methods of IR spectroscopy, elemental and GC-MS analysis, has been investigated. In addition, their fractional composition, density of fractions, as well as iodine number have been determined. Based on the results obtained, conclusions were drawn about the similarities and differences between pyrolysis oil and petroleum. It has been suggested that liquid pyrolysis products, after appropriate treatment, can be used as additives to petroleum products, which contributes not only to solving the problems of both the disposal of used tires, but also the depletion of readily available oil reserves.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>пиролиз</kwd><kwd>пиролизные масла</kwd><kwd>нефть</kwd><kwd>ГХ-МС метод</kwd></kwd-group><kwd-group xml:lang="en"><kwd>pyrolysis</kwd><kwd>pyrolysis oils</kwd><kwd>oil</kwd><kwd>GC-MS method</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Авторы выражают особую благодарность сотрудникам Института тепло- и массобмена им.
