Sažetak
Kompoziti od poliestera ojačani staklenim vlaknima (GFRPs) kao otpaci iz proizvodnje poliesterskih laminata su razloženi na 500, 550 i 600 °C u 70Kg inovativnim pilot postrojenjima koja obrađuju čitave delove. Prisustvo hidraulične zaštite garantuje sigurnost procesa. Uticaj maksimalne temperature procesa na tečenje i fizičko hemijske karakteristike pirolize proizvoda je ispitivan: frakcija ulja je analizirana pomoću GC-MS, viskozimetrom i XRF, dok je frakcija gasa praćena tokom čitavog procesa pirolize putem μ-GC. Značajna frakcija metana (20,7 vol %) i vodonika (11,5 vol %) je proizvedena. Čvrsti ostatak (staklena vlakna pokrivena tankim ugljeničnim slojem) je prošao kroz proces oksidacije na 500 i 600 °C u različitim vremenskim rasponima da bi se obezbedila čista staklena vlakna bez organskih ostataka. Efekti obe pirolize i koraci oksidacije staklenih vlakana, dobijenih u različitim procesnim uslovima, procenjivani su SEM-om i Raman spektroskopijom.
