Учитывая рост объёмов пластиковых отходов и сложность переработки вспененных материалов, был проведён анализ современных публикаций, посвящённых влиянию технологических параметров процесса на выход и состав жидких продуктов пиролиза. Особое внимание уделено воздействию температуры, продолжительности процесса в реакционной зоне. На основании анализа было установлено, что наиболее рациональным температурным режимом является диапазон 400–500°C. Именно в этих условиях достигается максимальный выход жидкой фракции, обогащённой ценными ароматическими соединениями: стиролом, бензолом, толуолом и этилбензолом. В результате выявлено, что отклонение от оптимальных температур ведёт либо к неполной деструкции полимера, либо к избыточному газообразованию. Отмечены преимущества пиролиза при переработке загрязнённых и вспененных полистирольных материалов. Дополнительно подчёркнута важность повышения эффективности технологий переработки полимерных отходов в условиях роста экологической нагрузки. Сделан вывод о высокой перспективности технологии для получения химического сырья и развития экономики замкнутого цикла при условии совершенствования систем сортировки, очистки и последующего фракционирования продуктов пиролиза.&lt;/p&gt;</abstract><kwd-group xml:lang="en"><kwd>recycling</kwd><kwd>pyrolysis</kwd><kwd>polystyrene</kwd><kwd>process temperature</kwd><kwd>residence time</kwd></kwd-group><kwd-group xml:lang="kk"><kwd>қайта өңдеу</kwd><kwd>пиролиз</kwd><kwd>полистирол</kwd><kwd>процесс температурасы</kwd><kwd>процесс ұзақтығы</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>переработка</kwd><kwd>пиролиз</kwd><kwd>полистирол</kwd><kwd>температура процесса</kwd><kwd>продолжительность процесса</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Perreard S, Boucher J, Gallato M.
