Abstract

Fosilna goriva su neobnovljiva i uzrokuju onečišćenje okoliša, što je razlog sve većoj proizvodnji energije iz obnovljivih izvora. Veliki potencijal za proizvodnju energije nalazi se u biomasi biljnog ili životinjskog porijekla, kao obnovljivom izvoru energije, a posebice biljkama i poljoprivrednim ostacima koji se mogu pretvoriti u kruta, tekuća ili plinovita goriva.
Invazivne biljne vrste zbog brzog širenja i razmnožavanja nepovoljno utječu na poljoprivrednu proizvodnju, bioraznolikost drugih vrsta, kao i na zdravlje ljudi. Kako bi se smanjila njihova populacija bez upotrebe herbicida, nakon mehaničkog uklanjanja mogu se koristiti kao potencijalna sirovina za dobivanje energije. Ambrozija pripada skupini stranih invazivnih vrsta, te se kao korov nalazi u poljoprivrednim kulturama, a pelud ambrozije izaziva alergije kod ljudi.
Cilj rada bio je istražiti mogućnost korištenja ambrozije kao sirovine za neposredno izgaranje i proces pirolize te utvrditi njen energetski potencijal. Obradom dobivenih podataka i interpretacijom rezultata, utvrđen je potencijal primjene procesa pirolize biomase ambrozije s ciljem proizvodnje bioulja kao energenta i biougljena kao proizvoda dodane vrijednosti.

Abstract (english)

Fossil fuels are non-renewable and can cause environmental pollution, which is why renewable energy production has a significant increase. Great potential for energy production is found in biomass of plant or animal source, as a renewable energy source, particular plants and agricultural residues that can be converted into solid, liquid, or gaseous fuels.
Invasive species because of their rapid spread and reproduction adversely affect agricultural production, biodiversity, and human health. In order to reduce their population without the use of herbicides, after mechanical removal, they can be used as a potential material for energy production. Ambrosia belongs to invasive species and found as a weed in agricultural crops, and their pollen causes allergies in humans.
The purpose of this study was to investigate the possibility of using ambrosia as a material for direct combustion and pyrolysis processto determine its energy potential. By processing the obtained data and interpreting the results, biomass potential of ragweed was determined to produce bio-oil as energy source and biochar as a value-added product.
