Apstrakt
Sinteza biodizela iz različitih biljnih ulja ostvaruje se transesterifikacijom triglicerida sa metanolom ili reakcijom koja se obično definiše kao metanoliza. Korišćenje ulja lošijeg kvaliteta, kao što je otpadno jestivo ulje (engl. waste cooking oil, WCO), prate neželjene sporedne reakcije kao posledica povećanog sadrđžaja slobodnih masnih kiselina (engl. free fatty acids, FFA) i vode. Prisustvo FFA u tim uljima obično zahteva fazu prethodne obrade pre nego što se ulje podvrgne procesu transesterifikacije. U ovom radu istražena je heterogeno kanalizovana metanoliza WCO sa i bez predtretmana. Uklanjanje FFA iz WCO obavljeno je korišćenjem samo kreča ili uz dodatak male količine metanola (molarni odnos FFA prema metanolu = 1:3). Dobijeni rezultati su pokazali da se u predtretmanu WCO krečom na 30 °C nakon 1 h može smanjiti sadržaj FFA za 72%, dok je određeno da je ravnotežni kapacitet adsorpcije 910 mg g-1. Predtretman adsorpcijom, kao jednostavnom operacijom, korišćenjem jeftinog kreča pod blagim uslovma, pozitivno je uticao na brzinu reakcije transesterifikacije s CaO∙ZnO kao katalizatorom, omogućujući postizanje preko 96 % prinosa biodizela za samo 15 min, u poređenju sa potrebnim vremenskim periodom od 1 h za postizanje istog prinosa iz ulja bez predtretmana. Nadalje, prethodno tretirano WCO omogućuje povećan broj ciklusa ponovne upotrebe katalizatora i ukupnu uštedu potrebne količine katalizatora. Ova studija je pokazala da je kreč ekonomičan, ekološki prihvatljiv i održiv materijal za uklanjanje FFA iz WCO.
