Abstract
Alternative fuels will play a crucial role in the complete decarbonisation of future energy systems based on renewable energy sources, where electricity is not a feasible solution. Therefore, the primary objective of this dissertation was to identify the most promising waste biomass and plastic feedstocks for the co-pyrolysis process with an aim to produce high-quality pyrolysis oil that could be further refined into alternative fuels compatible with existing standards for conventional fuels. This was done by examining the feedstock properties and running a series of experimental investigations. The results showed that sawdust, polystyrene and polypropylene are among the most promising feedstock to be utilised in co-pyrolysis. This evaluation is based on product quantity and quality from an individual and mixture analysis. In addition, the environmental impacts of the process are evaluated by carrying out a life cycle assessment. Finally, the discussion on methodology development for the prediction of product yield is given, which can serve as a base for future research. In summary, gathered observations from carried-out investigations can help better understand process dynamics, which is crucial for further commercialisation.
Abstract (croatian)
Alternativna goriva imat će ključnu ulogu u tranziciji budućih energetskih sustava baziranima na obnovljivim izvorima energije. Najviše se očekuje tamo gdje električna energija nije održivo rješenje. Stoga je primarni cilj ove disertacije bio identificirati otpadnu biomasu i plastiku sa najviše potencijala za proces ko-pirolize s ciljem proizvodnje visokokvalitetnog ulja koje se može rafinirati u alternativna goriva kompatibilna s postojećim standardima za konvencionalna goriva. To je učinjeno ispitivanjem inicijalnih svojstava sirovine i provođenjem niza eksperimentalnih istraživanja. Rezultati su pokazali da su piljevina, polistiren i polipropilen među sirovinama sa najviše potencijala za korištenje u ko-pirolizi. Ova procjena temelji se na količini i kvaliteti proizvoda dobivenih za individualne uzorke te odabranu mješavinu. Dodatno je provedena analiza utjecaja na okoliš evaluacijom štetnih emisija iz raznih faza procesa. Konačno je prezentirana i metodologija za razvoj modela predviđanja prinosa proizvoda koji može poslužiti kao osnova za buduća istraživanja tog problema. Ukratko, prikupljena zapažanja iz provedenih istraživanja mogu pomoći u boljem razumijevanju dinamike procesa, što je ključno za daljnju industrijalizaciju.
