Ülevaade
Uurimisrühm tegeleb kütuste analüüsiga, õhuemissioonide mõõtmisega, ioonsete vedelike alase uurimistööga ning pürolüüsiprotsesside uurimisega ning pürolüüsiprotsessi sisend- ja väljundvoogude karakteriseerimisega. See hõlmab koostise ja termodünaamiliste omaduste mõõtmist. Samuti tegeletakse tahkete ja vedelate ainete termilise käitumise alaste uuringutega (kalorimeetria ja termogravimeetriline analüüs) ja erinevate orgaanilistest ainetest koosnevate segude (õlid, vaigud, polümeerid) parameetrite (molaarmassi jaotus, reoloogilised omadused) ja termilise stabiilsuse uuringutega. Uurimisrühm tegeleb ka veepuhastustehnoloogiatega. Rühma tegevus on tihedalt põimunud jätkusuutliku energeetika ja kütuste uurimisrühma tööga. Koostööd tehakse ka Virumaa Kolledžiga.Rühma viimase aja teadustöö on seotud järgmiste teemadega:• Ioonsete vedelike alased uuringud• CO2 kasutamise alased uuringud;• Heitvee kvaliteedi parandamise alased uuringud;• Põlevkiviõlide fraktsioonide aururõhkude määramine;• Fenoolsete ühendite aururõhkude määramine;• Segude aururõhkude mudeldamine;• Pürolüüsi ja koospürolüüsi alased uuringud;• Termiline analüüs.
Tähtsamad tulemused
2023. aasta peamised tegevused olid seotud ioonsete vedelike alaste uurimistöödega, põlevkivi pürolüüsiprotsesside ja põlevkiviõli alaste uurimistöödega ning orgaaniliste materjalide karakteriseerimisega.
