Abstract

Globana svijest o klimatskim promjenama dovela je do značajnog pomaka prema obnovljivim izvorima energije. Biomasa energetskih kultura predstavlja velik potencijal kao sirovina za proizvodnju energije. Kulture poput miskantusa, divovske trske i divljeg prosa dijele nekoliko ključnih karakteristika koje ih čine savršenim energetskim usjevima. Jedna od najvažnijih jest da su kulture bogate ligninom i celulozom te su pogodne za pretvorbu u goriva. Jedan od tih procesa pretvorbe biomase u gorivo jest hidrotermalna karbonizacija koja se odvija u prisutnosti vode pod visokom temperaturom i tlakom u određenom vremenu. Nastali produkt je hidrougljen koji je bogat ugljikom, a može se koristiti kao kruto gorivo, poboljšivač tla, adsorbent zagađivača itd. U radu je utvrđena mogućnost hidrotermalne karbonizacije Miskantusa, Divljeg prosa i Divovske trske te je analiziran nastali hidrougljen. Isti se ističe kao koristan proizvod jer uključuje vrlo dobre karakteristike npr. sadržaj ugljika u prosjeku 50,07
% i prinos hidrougljena u prosjeku od 55,57 %.

Abstract (english)

Global awareness of climate change has led to a significant shift towards renewable energy sources. Biomass of energy crops represents a great potential as a raw material for energy production. Crops like Miscanthus, Arundo donax and Panicum virgatum share several key characteristics that make them perfect energy crops. One of the most important is that the cultures are rich in lignin and cellulose and are suitable for conversion into fuels. One of these processes of converting biomass into fuel is hydrothermal carbonization, which takes place in the presence of water under high temperature and pressure for a certain time. The resulting product is hydrochar, which is rich in carbon, and can be used as a solid fuel, soil improver, pollutant adsorbent, etc. The paper determined the possibility of hydrothermal carbonization of Miscanthus, Arundo donax and Panicum virgatum, and analyzed the resulting hydrochar. It stands out as a useful product because it includes very good characteristics, for example carbon content of 50,07 % on average and hydrocarbon yield on average of 55,57 %.
