The influence of reaction conditions (medium, temperature, vapor residence time, polystyrene concentration) on polymer conversion and product distribution was studied. It was found that the polymer conversion is close to 100%, while ethylbenzene, benzene, and toluene are the main products of its transformation. The maximum yield of ethylbenzene (80%) was achieved at 550 \u00b0C, vapor residence time 1\u20132 s, polystyrene concentration 10%, and heavy cycle oil as the medium. The influence of zeolite topology on product distribution was explored. The possible mechanism of polystyrene pyrolysis was proposed.<\/jats:p>","DOI":"10.3390\/polym15020290","type":"journal-article","created":{"date-parts":[[2023,1,6]],"date-time":"2023-01-06T02:20:30Z","timestamp":1672971630000},"page":"290","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["Catalytic Pyrolysis of Polystyrene Waste in Hydrocarbon Medium"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8102-8624","authenticated-orcid":false,"given":"Konstantin I.","family":"Dement\u2019ev","sequence":"first","affiliation":[{"name":"Topchiev Institute of Petrochemical Synthesis, Russian Academy of Sciences (RAS), 119991 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8926-0818","authenticated-orcid":false,"given":"Stanislav P.","family":"Bedenko","sequence":"additional","affiliation":[{"name":"Topchiev Institute of Petrochemical Synthesis, Russian Academy of Sciences (RAS), 119991 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yulia D.","family":"Minina","sequence":"additional","affiliation":[{"name":"Topchiev Institute of Petrochemical Synthesis, Russian Academy of Sciences (RAS), 119991 Moscow, Russia"},{"name":"Faculty of Chemical Technology and Ecology, Gubkin Russian State University of Oil and Gas, 119991 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aniya A.","family":"Mukusheva","sequence":"additional","affiliation":[{"name":"Topchiev Institute of Petrochemical Synthesis, Russian Academy of Sciences (RAS), 119991 Moscow, Russia"},{"name":"Faculty of Chemical Technology and Ecology, Gubkin Russian State University of Oil and Gas, 119991 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Olga A.","family":"Alekseeva","sequence":"additional","affiliation":[{"name":"Topchiev Institute of Petrochemical Synthesis, Russian Academy of Sciences (RAS), 119991 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Timur A.","family":"Palankoev","sequence":"additional","affiliation":[{"name":"Topchiev Institute of Petrochemical Synthesis, Russian Academy of Sciences (RAS), 119991 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,6]]},"reference":[{"key":"ref_1","unstructured":"Statista (2022, December 23).
