Abstract

Ograničeni resursi fosilnih goriva te onečišćenje okoliša ubrzali su pronalazak i uporabu novih alternativnih goriva. Obnovljiv izvor energije, biodizel, smatra se ekološki prihvatljivim zamjenskim gorivom za dizelske motore. Kada se proizvodi iz otpadnih sirovina iz prehrambene industrije, predstavlja i rješenje za nezbrinuti prehrambeni otpad. Primjerom takvog otpada je komina masline, koja ima veliki potencijal zbog dobrih termokemijskih karakteristika. U radu je istražena sinteza biodizela iz ulja komine masline metodom transesterifikacije pomoću homogenih bazičnih katalizatora – KOH i NaOH, te heterogenog katalizatora – CaO, u magnetskoj miješalici. KOH se pokazao kao najučinkovitiji, a CaO kao najmanje učinkovit katalizator. Dobiveni sirovi biodizel je podvrgnut pročišćavanju sa ekološki prihvatljivim niskotemperaturnim eutektičkim otapalom na bazi kolin klorida.

Abstract (english)

Limited fossil fuel resources and environmental pollution have accelerated the invention and use of new alternative fuels. As a renewable energy source, biodiesel is considered an environmentally friendly alternative fuel for diesel engines. When produced from food industry by-products and wastes, it also presents a solution for unmanaged food waste. Olive pomace is one of those waste feedstocks, and it has great potential due to its good thermochemical characteristics. This paper investigates biodiesel synthesis from olive pomace oil by transesterification using two homogeneous basic catalysts – KOH and NaOH, and one heterogeneous catalyst – CaO. The highest quality biodiesel was obtained using KOH, while CaO exhibited the lowest efficiency. The obtained crude biodiesel was then subjected to purification with an environmentally friendly, low-temperature deep eutectic solvent based on choline chloride.
