Proizvodnja biogoriv iz lignocelulozne biomase

diplomsko delo

Nanja Brelih (Author), Igor Plazl (Mentor)

Abstract

Delo opisuje različne tehnike predelave biomase v različna goriva (biodizel, olja, plin). Poudarek pa je na procesu hidrolize, saj omogoča sintezo najobetavnejših molekul, kot sta levulinska kislina (LA) in gama-valerolakton (GVL). Levulinsko kislino je z različnimi postopki mogoče pretvoriti v difenolno kislino, metiltetrahidrofuran (MTHF), GVL in druge molekule, ki se jih uporablja kot polimere, herbicide, farmacevtske komponente, biogoriva in topila. GVL pa je mogoče dodajati v že obstoječa tradicionalna goriva in s tem zmanjšati emisije ob vžigu. Uporablja se tudi kot zeleno topilo za konverzijo biomase, zaradi svoje netoksičnosti in zeliščnega vonja pa se uporablja tudi v nekaterih prehranskih aditivih in parfumih.

Secondary title:	Production of biofuels from lignocellulosic biomass
Secondary abstract:	The thesis describes various methods for the conversion of biomass to different fuels (biodiesel, oils, gas). The emphasis is on a method of hydrolysis that enables the production of various potential platform molecules such as levulinic acid (LA) and gamma-valerolactone (GVL). Levulinic acid can then be converted to phenolic acid, methyl tetrahydrofuran (MTHF), GVL, and other molecules that can be used as polymers, herbicides, pharmaceutical components, biofuels, and solvents. GVL can be blended in traditional fuels and also reduces CO2 emissions in comparison with fossil fuels. It is widely used as a green solvent for biomass conversion. Because of its distinctive herbal odor and non-toxicity, it is also widely used in food additives and perfumes.
