Учитывая рост объемов пластиковых отходов и сложность переработки вспененных материалов, было проанализировано влияние температуры и длительности процесса на формирование жидких продуктов с высокой добавленной стоимостью. На основании анализа было установлено, что наиболее рациональным температурным режимом является диапазон 400–500 °C. Именно в этих условиях достигается максимальный выход жидкой фракции, обогащенной ценными ароматическими соединениями: стиролом, бензолом, толуолом и этилбензолом. В результате выявлено, что отклонение от оптимальных температур ведет либо к неполной деструкции полимера, либо к избыточному газообразованию. Сделан вывод о высокой перспективности пиролиза для химического рециклинга при условии оптимизации очистки полистирольных отходов и подтверждения экономической эффективности технологии&lt;/p&gt;</abstract><kwd-group xml:lang="en"><kwd>recycling, pyrolysis, polystyrene, process temperature, process duration</kwd></kwd-group><kwd-group xml:lang="kk"><kwd>қайта өңдеу, пиролиз, полистирол, процесс температурасы, процесс ұзақтығы</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>переработка, пиролиз, полистирол, температура процесса, продолжительность процесса</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>1.
