20.500.12556/DKUM-89849 Waste Lignocellulosic Biomass as a Source for Bioethanol Production Synthetically produced biofuels play a critical role in the energy transition away from fossil fuels. Biofuels could effectively lower greenhouse gas (GHG) emissions and contribute to better air quality. One of these biofuels is bioethanol, which could act as a gasoline replacement. For this purpose, a simulation of bioethanol production through lignocellulosic biomass fermentation, focused on distillation, was carried out in simulation software Aspen Plus. Since the possibility of absolute ethanol production through distillation is limited by the ethanol–water azeotrope, pressure swing distillation (PSD) was used to obtain fuel-grade ethanol (EtOH) with a fraction of 99.60 wt.%. The flowsheet was optimised with NQ analysis, which is a simple optimisation method for distillation columns. We found that the PSD has the potential to concentrate the EtOH to a desired value, while simultaneously removing other unwanted impurities whose presence is a consequence of pretreatment and fermentation processes. bioethanol distillation lignocellulosic biomass azeotrope Aspen Plus bioetanol distilacija lignocelulozna biomasa true false true MDPI Angleški jezik Slovenski jezik https://www.mdpi.com/journal/suschem © 2024 by the authors Članek v reviji 2024-08-14 11:32:44 2024-08-14 11:32:45 2025-07-23 03:11:05 0000-00-00 00:00:00 2024 0 0 12 str. št. 1 let. 5 Feb. 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2024-01-24 2024-02-24 2024-02-28 620.9 187697667 10.3390/suschem5010001 2673-4079 suschem-05-00001.pdf suschem-05-00001.pdf 1 E5F93AB9AEDCA46956D5881BFDA33A5E 99385355c5c216bb121d2a079cebff6bfbc44e741f4914ad9e285d9cd6cc9575 10a8c188-66d4-11f0-b4a7-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=193915 https://www.mdpi.com/2673-4079/5/1/1 0 153615d8-66d4-11f0-b4a7-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=193916 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
