Abstract:

Biodiesel production from non-edible oil seed has gained tremendous attention around the globe due to its unique features that are biodegradable, cost-effective and easily available fuel as compared to fossil fuels. The current study focuses on the utilization of novel non- edible, highly rich oil seeds i-e Acacia modesta Wall. (Seed oil 60%; FFA 0.3mg KOH/g) for synthesizing eco-friendly biodiesel. A novel nano-catalyst Zinc doped Copper Oxide (Zn (CuO)) (synthesized hydrothermally) have been synthesized, and characterized through SEM (Scanning Electron Microscope), XRD (X-rays Diffraction), XPS (X-ray Photoelectron Spectroscopy), FT-IR (Fourier Transform Infrared Spectroscopy)) and employed successfully for producing biodiesel through single step transesterification. This catalyst exhibits excellent catalytic activities (Acacia modesta biodiesel 89.5% yield), recyclability (3 times reusability of Zn (CuO)) and stability making them sustainable candidates for synthesizing biodiesel under ideal conditions. Zinc-doped copper oxide (Zn (CuO) nano-catalyst yield 89.5% Acacia modesta Wall. seed oil into biodiesel using 1:6 methanol oil, catalyst dosage of 0.5 wt %, at 65°C temperature, and time of reaction as 180 min). The synthesized biodiesel was characterized via latest techniques FT-IR (Fourier Transform Infrared Spectroscopy), NMR (Nuclear Magnetic Resonance) and GC-MS (Gas Chromatography-Mass Spectrometry) etc to check the presence of methyl ester groups. The study confirms Acacia modesta biodiesel meets international standards (EN 14214, ASTM D6751, and GB/T 20828), proving suitable for automotive use and eco-friendly energy. It highlights the potential of Acacia feedstock with Zn-CuO nano- catalysts for sustainable large-scale biodiesel, recommending cultivation on barren lands to boost ecosustainability and innovation.
