Experimental and Computational Investigations of Biodiesel Production from Castor Oil: Intensifying Transesterification with a Lithium-Doped Salmon Fish Bone-Supported Lanthanum Oxide Composite Catalyst in a Micro-Reactor

Опубликована: Янв. 1, 2024

Ensuring efficient and sustainable biodiesel production is essential for addressing environmental concerns meeting global energy demands. This study aims to optimize the transesterification of castor oil through development a distinctive Li-doped salmon fish bone-supported La2O3 composite catalyst within micro-reactor setup. The optimal (3%Li/SFB-La) was thoroughly evaluated its physicochemical features employing range characterization techniques, including XRD, XPS, BET, FESEM, TEM, TGA/DSC, FT-IR. According DFT calculations, function Li dopants, which have lower electronegativity (0.98) compared La (1.1), enhance charge transfer capability sites, thereby increasing their reactivity with triglycerides. In interim, we determined optimized reaction conditions: 6:1 methanol/oil molar ratio 5 wt. % loading at 338 K. Under these parameters, an impressive 99.38% conversion achieved 1.5 hours. Furthermore, 3%Li/SFB-La exhibited remarkable stability, retaining high activity throughout 7 cycles without any significant loss efficacy. Moreover, kinetics were investigated, revealing rate constant 1.17 h−1 activation 14.46 kJ mol−1.
