“…From the graph below, it is noticed that yield of 1:1 is 45%, 2:1 is 55%, 3:1 is 65%, 4:1 is 75% and 5:1 gave 88% which is the optimum yield, then a decrease in yield was observed from 6:1 methanol to oil volume ratio. This result agrees with the already reported findings of some researchers [32,33]. However, it is worthy to note that the increase in alcohol to oil volume ratio above 5: 1 declines the biodiesel conversion.…”

Magnetic iron nanoparticles (Fe3O4) were synthesized and characterized using Fourier Transformed Infrared ((FT-IR), UV-Visible spectrophotometer, Scanned Electron Microscopy (SEM) equipped with an Energy Dispersive X-ray spectrometer (EDX), and X-ray Diffraction (XRD). The synthesized nano catalyst was used in the transesterification of mahogany seed oil with methanol. The optimized reaction conditions gave a reaction yield of 88% at a catalyst concentration of 1.5% wt., a volume ratio of methanol to oil of 5:1, a reaction temperature of 60 °C, and a reaction time of 120 minutes. The Fe3O4 nanoparticles was regenerated from the mixture and reused for various circles by applying the optimum conditions obtained during the present study. The results showed that the biodiesel yield decreased by increasing the number of cycles when the regenerated catalyst was used. However, good conversion (81.9%) was obtained up to the 5th cycles. The elemental analysis of the synthesized magnetic iron nanoparticles Fe3O4) revealed the highest proportion of iron with 64.37 and 74.40% for atomic and weight concentration respectively, followed by oxygen with 34.27 and 24.50% for atomic and weight concentrations respectively. It could be concluded that the synthesized nano catalyst would serve as an excellent catalyst for the transesterification of vegetable oils.

“…Nanda et al (2014) [6] used phosphoric acid (H3PO4) to separate soap and fatty acids contained in crude glycerol sourced from palm oil; the optimum pH obtained was 5. Meanwhile, Sinaga et al (2018) [12] also conducted the same thing, but the vegetable oil used is coconut oil, and the optimum pH is 7. Differences in raw material sources can cause differences in the refining process (pH) conditions in refining crude glycerol from biodiesel by-products.…”

The government program requires the use of biodiesel B35, which is 35% fatty acid methyl ester and 65% diesel oil from petroleum, which would impact the rise of biodiesel production and is accompanied by an increase in the by-product of crude glycerol. Crude glycerol requires purification to increase its selling value. This product still contains a lot of impurities such as methanol, soap, catalyst, fatty acids, and water. Crude glycerol, a by-product of making biodiesel based on palm oil and castor oil, has a purity of 39.10 and 37.30%. In this research, purification of crude glycerol was carried out using 10% w/v activated carbon. The results of glycerol after purification were 64.90 and 66.90%, it shows that the addition of activated carbon can absorb impurities contained in glycerol. The increase in levels from 37.30 to 64.90% and 66.90% due to the loss of water, alcohol, residue base (KOH), soap and fatty acids. It can be concluded that activated carbon is quite effective for the glycerol purification process with an addition of 10% (w/v). A further process is required, namely separation by distillation, to obtain glycerol with a purity above 80% to comply with SNI 7182-2015 standards.

“…El incremento en la producción de biodiesel a escala mundial ha traído como consecuencia un aumento considerable de las existencias de glicerina, la cual se genera como subproducto de la síntesis de este biocombustible [1] [2]. Sin embargo, este tipo de glicerina no puede reemplazar la del grado farmacéutico USP (99.5%) debido a los altos costos que implica la purificación [3] [4]. La glicerina que se extrae de la corriente del biodiesel es tóxica por la presencia de metanol, jabones y sales orgánicas e inorgánicas [5].…”

En esta investigación, glicerina grado técnico proveniente de la industria del biodiesel se esterificó para obtener mono, di, tri acetil gliceroles. Se empleo ácido acético glacial y resina de intercambio iónico Amberlyst®15 como catalizador heterogéneo para llevar a cabo la reacción. Acetil gliceroles fueron probados para reemplazar parcialmente hasta 10 partes en peso de aceite nafténico en formulaciones de caucho SBR1502 reforzado con sílica precipitada. Se uso peróxido de dicumilo para curar los compuestos. Se realizaron ensayos de reometría a los compuestos antes de ser curados. La resistencia a la tracción, elongación a rotura y resistencia al desgarre fueron evaluados para los compuestos curados. Se determinó que la adición de 10 phr de acetil gliceroles afectó levemente el torque mínimo y la resistencia a la tracción.
