Abstract

Ljudsku populaciju zadnjih desetljeća okupiraju problemi vezani za akumulaciju otpada i globalno zatopljenje. Osim toga, porast broja stanovnika zahtijeva sve veću potrebu za energijom koja se do sada dobivala uglavnom iz neobnovljivih izvora. U novije vrijeme prerada sirovina od ugljika za proizvodnju topline, kemikalija ili goriva nudi alternativu odlagalištima otpada i pruža dodatak upotrebi fosilnih goriva. Korištenje biomase omogućava i zapošljavanje, povećanje lokalne i regionalne gospodarske aktivnosti te ostvarivanje dodatnog prihoda u poljoprivredi, šumarstvu i drvnoj industriji kroz prodaju goriva iz biomase. Osim ekonomske, korištenje biomase za proizvodnju goriva, donosi i brojne ekološke pogodnosti poput CO2 neutralnosti, smanjenih emisija dušikovih i sumporovih oksida, ali i korištenje energije iz obnovljivih izvora. Upravo proces pirolize omogućuje razlaganje biomase bez prisutnosti kisika kako bi nastali glavni produkti: bio-ugljen, bio-ulje i pirolitički plin. Nastanku svakog pojedinog produkta pogoduju različiti procesni parametri i vrsta biomase koja se u postupku koristi, a tim se faktorima može upravljati u cilju maksimiziranja željenog produkta. Svaki od njih pojedinačno ima veliki potencijal te nalazi raznoliku primjenu u svakodnevnom životu.

Abstract (english)

The human population has been occupied in recent decades by problems related to waste accumulation and global warming. In addition, population growth requires an increasing need for energy, which has so far been obtained mainly from non-renewable sources. More recently, the processing of carbon raw materials to produce heat, chemicals or fuels offers an alternative to landfills and provides an adjunct to the use of fossil fuels. The use of biomass also enables employment, increasing local and regional economic activity and generating additional income in agriculture, forestry and the wood industry through the sale of biomass fuels. In addition to economic, the use of biomass for fuel production brings a number of environmental benefits such as CO2 neutrality, reduced emissions of nitrogen and sulfur oxides, but also the use of energy from renewable sources. It is the process of pyrolysis that allows the decomposition of biomass without the presence of oxygen, in order to form the main products: bio-coal, bio-oil and pyrolytic gas. The formation of each individual product is favored by different process parameters and the type of biomass used in the process, and these factors can be managed in order to maximize the desired product. Each of them individually has great potential and finds various applications in everyday life.
