The study investigates new raw materials for biodiesel production, covering oil extraction, ester production, and the evaluation of physicochemical properties and engine performance. Biodiesels from rapeseed, sunflower, camelina, palm oils, and animal fats were produced using the GW-201 reactor developed by Professor Grzegorz Wcisło. The research compares these biodiesels with diesel fuel, following standards PN-EN14214 +A2:2019–05 and PN-EN-590:2018. First-generation biofuels include rapeseed methyl ester (RME), sunflower (SME), camelina (CME), and palm oil (PME), while animal fat methyl ester (AFME) represents second-generation biofuels. The study identifies significant differences in fatty acid composition across biodiesels and assesses key properties such as density, viscosity, calorific value, cetane number, and combustion characteristics. All biodiesels met the EN 14,214 ester content requirement (>96.5% w/w). Results highlight the importance of raw material choice in optimizing biodiesel properties to match diesel fuel for reliable engine performance and reduced environmental impact.

摘要

The study investigates new raw materials for biodiesel production, covering oil extraction, ester production, and the evaluation of physicochemical properties and engine performance. Biodiesels from rapeseed, sunflower, camelina, palm oils, and animal fats were produced using the GW-201 reactor developed by Professor Grzegorz Wcisło. The research compares these biodiesels with diesel fuel, following standards PN-EN14214 +A2:2019–05 and PN-EN-590:2018. First-generation biofuels include rapeseed methyl ester (RME), sunflower (SME), camelina (CME), and palm oil (PME), while animal fat methyl ester (AFME) represents second-generation biofuels. The study identifies significant differences in fatty acid composition across biodiesels and assesses key properties such as density, viscosity, calorific value, cetane number, and combustion characteristics. All biodiesels met the EN 14,214 ester content requirement (>96.5% w/w). Results highlight the importance of raw material choice in optimizing biodiesel properties to match diesel fuel for reliable engine performance and reduced environmental impact.
