Abstract

Problem suvremenog svijeta je sve veća potrošnja energije. Nestašicom neobnovljivih izvora energije sve više se okreće obnovljivim izvorima energije, te se očekuje sve veće iskorištavanje biomase (otpad, ostaci industrije).
Somina (Juniperus phoenicea) je zimzeleni grm ili niže stablo, koje raste od 5 do 8 metara. Može se pronaći u području Mediterana, a u Hrvatskoj stvara velike probleme na otoku Pagu koji je poznat po uzgoju ovaca. Naime, navedena vrsta zauzima sve veći prostor za ispašu te uništava ljekovito bilje.
Cilj rada bio je utvrditi energetsku iskoristivost biljne vrste somine nakon mehaničkog uklanjanja iz prirode. Kako bi se provjerila energetska iskoristivost, provedene su sljedeće analize: analiza sadržaja vode, pepela, sadržaj koksa, fiksiranog ugljika, hlapivih tvari te sadržaj celuloze i hemiceluloze kao i gornja ogrjevna vrijednost. Nakon analiza ulaznih sirovina, provela se piroliza uzoraka pri temperaturi od 400 °C, pri čemu se izvagao udio bioulja i biougljena.

Abstract (english)

The problem of the contemporary world is increased energy consumption. Because of the shortage of non-renewable energy sources, people are shifting to renewable energy sources and, therefore, the growing exploitation of biomass is expected (waste, remains of the industry).
Phoenician juniper is an evergreen bush or lower tree reaching from 5 to 10 meters in height. It can be found throughout the Mediterranean region and in Croatia, it creates problems in places such as Pag, which is known for sheep breeding. Phoenician juniper takes up growing places for grazing and it destroys healing herbs.
The goal of this paper was to determine energy utilization od plant species Phoenician juniper after their mechanic removal from nature. Screening of energy usability is made with the following analysis: a content analysis of water, ash, coke, fixed carbon, volatile substances, cellulose and hemicellulose content, and their top calorific value. After the analysis of input raw materials, pyrolysis of samples is made at 400 degrees, and percentage of bio-oil and biofuel is weighted.
