Abstract

Fosilna goriva danas predstavljaju veliki problem i zagađenje u okolišu, narušavaju bioraznolikost, uništavaju tla i povećavaju emisiju štetnih plinova u atmosferu. Proizvodnjom i korištenjem biomase u energetske svrhe smanjuje se emisija štetnih tvari i doprinosi se zaštiti tla i voda te povećanju bioraznolikosti. Biomasa je vrlo prihvatljivo gorivo s gledišta utjecaja na okoliš jer sadrži vrlo malo ili čak uopće ne sadrži brojne štetne tvari kao što su sumpor, teški metali i sl., koje se nalaze u fosilnim gorivima.
Veliki problem predstavljaju invazivne korovne vrste koje umjesto da se uklanjaju kemijski ili spaljuju mogu imati veliki energetski potencijal i tako poslužiti kao kvalitetna sirovina za proizvodnju biogoriva i bioulja.
Cilj istraživanja bio je utvrditi mogućnost korištenja biomase invazivne biljne vrste japanski dvornik (Reynoutria japonica) nakon njegovog uklanjanja iz prirode mehaničkim putem. Biomasa ove biljke koristila se kao sirovina za izravno izgaranje, odnosno utvrdio se njegov energetski potencijal s ciljem proizvodnje toplinske energije. Odredio se potencijal primjene procesa pirolize s ciljem proizvodnje bioulja kao energenta i biougljena kao proizvoda dodane vrijednost.

Abstract (english)

Fossil fuels today pose a major problem and pollution for the environment, they disrupt biodiversity, destroy soil and increase the emission of harmful gases into the atmosphere. Production and use of biomass for energy purposes reduces emission of harmful substances, and contributes to soil and water protection, as well as the increase of biodiversity. Biomass is a highly acceptable fuel from the environmental impact aspect, because it contains very little or none harmful substances - sulphfur, heavy metals, etc., which are found in fossil fuels.
A major problem is invasive weed species which instead of being chemically removed or burning can have a high energy potential and serve as a quality raw material for the production of biofuels and bio-waste.
The aim of the research was to determine the possibility of using invasive plant species biomass Japanese counterpart (Reynoutria japonica) after its removal from nature by mechanical means. The biomass of this plant was used as raw material for direct combustion, and its energy potential was determined with the aim of producing heat. Potential of the pyrolysis process was determined with the aim of producing biooil as an energy source and biocoal as a value added product.
