Biodiesel has received tremendous attention as a sustainable energy source. This review presents an overview of various catalysts utilized in biodiesel production and compares their potential for producing biodiesel. Presented here are the excellent features while highlighting drawbacks. For instance, with homogeneous base is easy but it can only be used refined oils having low levels free fatty acid (FFAs). When esterification, causes reactor corrosion. Water FFAs do not affect heterogeneous catalysts. Thus, transesterification triglycerides into converting through esterification catalyzed more efficiently using catalyst. Biocatalysts also being to produce from high FFAs. However, biocatalysts suitable industrial application due serious mass transfer limitations. yield conversion were compared over this paper. Also presented effects different reaction parameters on The correct interplay factors like temperature, time, alcohol-to-oil molar ratio, catalyst loading produces optimal process conditions that give highest yield.

This study investigates the kinetic and thermodynamic parameters of thermal degradation biodiesel produced from low-grade palm kernel oil. In this work, was through a two-step transesterification oil having free fatty acid content 5.7%. The first step uses 25% methanol (wt% oil) 1% sulfuric to reduce acids 0.3% within 30 min reaction time. second step, methanol-to-oil molar ratio 6:1 0.6% KOH yielded conversion 96.96% after analyzed using Fourier Transform Infrared spectroscopy, gas Chromatography tandem mass spectrometry, nuclear magnetic resonance spectroscopy (1H and13C), thermogravimetric analysis. stability assessed decomposition isoconversional techniques. Flynn-Wall-Ozawa, Kissinger-Akariha-Sunose, Starink models were used evaluate parameters, while Coats Redfern technique forecast most probable mechanism degradation. average activation energies 108.60 kJ mol−1, 107.75 mol−1 95.77 Kissinger-Akahira-Sunose, methods, respectively. FWO method best described decomposition, with highest R2 values 0.94 for 0.93 results obtained (ΔH = 218.48 kJ.mol−1, ΔG 200.05 kJ.mol−1 ΔS 27.10 J.mol−1.K−1) revealed that an endothermic, non-spontaneous process governed by three-dimensional diffusion mechanism.
