Abstract

Rastuća svijest o klimatskim promjenama potakla je znanstvenike na razvoj obnovljivih energetskih izvora kako bi zaštitili Zemlju, nas i buduće naraštaje života. Jedan od glavnih problema opasnih klimatskih promjena su staklenički plinovi nastali kao posljedica sve većeg broja prijevoznih sredstava. Emisija stakleničkih plinova po kilometru putovanja osobnim vozilom u porastu je za 13% u posljednjem desetljeću. Rješenje za izgaranje dizela i benzina u prijevoznim sredstvima je biorazgradiva, netoksična i ekološki prihvatljiva alternativa – biodizel. Za proizvodnju visoko kvalitetnog biodizela potrebno je ukloniti nečistoće, vodu i metale iz masti i ulja, sirovina za dobivanje biodizela. U ovom eksperimentalnom radu cilj je bio smanjiti koncentraciju metala u otpadnim životinjskim mastima i otpadnim jestivim uljima metodom ekstrakcije niskotemperaturnim eutektičkim otapalima pri temperaturi 60 °C tijekom dva sata kako bi se dobila što kvalitetnija sirovina za dobivanje biodizela. Na temelju dobivenih rezultata odabrano je najučinkovitije otapalo za ekstrakciju metala iz otpadnih životinjskih masti i otpadnih jestivih ulja.

Abstract (english)

Increasing awareness of Earth's climate change inspires scientists to find renewable energy sources to protect the Earth, us and the future generations of life. One of the major problems of dangerous climate change is greenhouse gases as a consequence of an increasing number of vehicles. The greenhouse gas emissions per kilometer by passenger car increased 13% in the last decade. The solution for diesel and gasoline combustion in transportation is a biodegradable, non-toxic and ecologically acceptable alternative – biodiesel. In order to achieve high quality biodiesel, it is necessary to remove impurities, water and metals from fats and oils, raw material for obtaining biodiesel. In this experimental work, the aim was to reduce the concentration of metals in animal waste fats and edible waste oils by extracting the metals with low-temperature eutectic solvents at 60 °C for two hours to get the best quality raw material for obtaining biodiesel. Based on the obtained results, the most efficient solvent for the extraction of metals from waste animal fat and waste edible oils was selected.
