Performance of Different Catalysts on Biodiesel Production from <i>Jatropha curcas</i> Oil through Transesterification

The purposes of the work to study the fatty acid methyl ester production by transesterification of Jatropha curcus oil with different catalysts where methanol was used as solvent. Jatropha oil having high free fatty acids FFA (14.02%) was processed in two steps. First step is acidcatalyzed esterification by using 1% H2SO4, 40% methanol-to-oil to produce methyl esters by lowering the acid value, and next step is different base-catalyzed transesterification. As part of ongoing efforts to investigate different homogeneous, heterogeneous and solid acid catalysts for biodiesel synthesis, the catalytic activity of KOH, NaOH, Ca(OH)2, activated Ca(OH)2, Hß zeolite and montmorillonite were studied for the transesterification of Jatropha oil. Among these catalysts, performance of catalysts order are KOH > NaOH > activated Ca(OH)2 >Ca(OH)2> montmorillonite> Hß zeolite.Key words: Jatropha oil; Transesterification; Biodiesel; FFA; CatalystsDOI: 10.3329/bjsir.v45i2.5702Bangladesh J.

Esterification Reactions

Biodiesel, an environmentally friendly biomass-based fuel, is gaining popularity globally as a cost-effective way to meet rising fuel demand. However, the high cost of raw materials and catalysts continues to drive up biodiesel production. An alternative feedstock with a heterogeneously catalyzed reaction could be the most cost-effective way to stabilize industrial biodiesel growth. Understanding these issues led to the idea of using waste palm oil as a feedstock for biodiesel production. While using waste materials as feedstock for biodiesel is an elegant solution, converting high free fatty acids (FFA) directly into methyl esters has some drawbacks. High FFA processes (acid esterification, then base transesterification) are costly. The commercial processes currently use a homogeneous system with sulfuric acid to catalyze both esterification and transesterification. However, heterogeneous solid acid catalysts are preferred over hazardous mineral acids for high FFA esterification because they are less corrosive, produce less waste, and are easier to separate from reactants and products by filtration, recovery, and reusability. Heterogeneous acid catalysts can also simultaneously catalyze transesterification and esterification reactions. Thus, new waste-based support for heterogeneous catalysts (solid acid catalysts) is required to convert waste oils into biodiesel.

Xrd Patterns

Rare earth modified SO2-4/ZrO2 solid acid catalysts were prepared by coprecipitation and impregnation methods respectively. The properties of the samples were characterized by XRD (X-ray diffraction), FT-IR (Fourier transform infrared spectroscopy). And their catalytic performances were evaluated and investigated by transesterification of waste oil with methanol. The results showed that the catalyst containing 4% Ce and calcined at 550°C displayed the highest production rate and the better reuse ability than the others. 63.5% yield of fatty acid methyl ester was achieved. An analysis of XRD patterns reveal that the incorporation of rare earth into tetragonal zirconia stabilizes the compound, and the calcination at 550°C increases the reactivity of the catalyst by producing a greater fraction of active tetragonal zirconia. It can be seen from the FT-IR spectra that superacids structures are formed in the catalysts and the acidity is strengthened remarkably and the activated centre of the catalyst were increasesed.
