摘要: Piroliza, kao jedna od tehnika hemijske reciklaže plasticnih materijala, danas izaziva sve veca intersovanja ekoloski i ekonomski prihvaljiva opcija obrade otpadnih materijala. Istraživanja ovih procesa se provode pri razlicitim eksperimentalnim uslovima, u vrstama reaktora sa sirovinama, sto cini poređenje direktnu primjenu procesnih parametara dosta složenim. U ovom radu dati su rezultati istraživanja uticaja temperature, intervalu od 450°C do 525°C, na prinos pirolize smjese otpadne plastike sastavu: polipropilen 40%, polietilen niske gustine 35% visoke 25%. provedena pilot reaktoru fiksnim slojem koji je razvijen za ovu namjenu. Rezultati provedenih pokazuju da temperaturi 500°C postiže potpuna konverzija sirovine vremenu 45 min, uz maksimalni pirolitickog ulja 32,80%, gasovitih produkata 65,75% cvrsti ostatak 1,46%. Sa daljim porastom temperature raste produkata, racun smanjenja prinosa ulja. Dobijeno piroliticko ulje ima visoku toplotnu moc (45,96 МЈ/kg), te tom pogledu potencijal primjene alternativno gorivo.
