Rapeseed as a raw material for biodiesel production

Abstract

Rapeseed seeds contain 40-48% of oil. Introduction of rapeseed into the field crop production means a switch from excess cereal production to a new industrial and energy crop. Rapeseed matures and becomes ready for harvest early, leaving ample time for quality soil preparation for the subsequent crop. Also, it leaves field free of weeds. These features make rapeseed a desirable component of crop rotation. Combustion of plant oils releases large amounts of energy. Biodiesel obtained from plant oils substitutes the liquid fossil fuels, and it is ecologically more acceptable than the fossil diesel fuel.

Seme uljane repice sadrži 40-48% ulja. Gajenjem uljane repice preusmerava se poljoprivredna proizvodnja sa prekomernih žitarica na nove industrijske i energetske kulture. Uljana repice stiže rano za žetvu, ostavljajući dovoljno vremena za blagovremenu i kvalitetnu obradu za naredne useve i ostavlja čisto zemljište bez korova. Zbog navedenih osobina je dobra komponenta u plodoredu. Sagorevanjem biljnih ulja oslobađa se velika količina energije. Biodizel se dobija preradom ovih ulja i koristi za zamenu fosilnih, tečnih goriva i ekolološki je prihvatljiviji energent od mineralnog dizela.
