“…where m i is the mass of internal standard added to the sample, A i is the peak area of internal standard, m b is the mass of the biodiesel sample, and A b is the peak area of the biodiesel sample [9, 10]. The physical and chemical properties of FAME including kinematic viscosity, density, flash point, cloud point, pour point, acid value, and water content were analyzed according to ASTM methods [11].…”

The waste shell was utilized as a bioresource of calcium oxide (CaO) in catalyzing a transesterification to produce biodiesel (methyl ester). The economic and environmen-friendly catalysts were prepared by a calcination method at 700–1,000°C for 4 h. The heterogeneous catalysts were characterized by X-ray diffraction (XRD), X-ray fluorescence (XRF), scanning electron microscopy (SEM), and the Brunauer-Emmett-Teller (BET) method. The effects of reaction variables such as reaction time, reaction temperature, methanol/oil molar ratio, and catalyst loading on the yield of biodiesel were investigated. Reusability of waste shell catalyst was also examined. The results indicated that the CaO catalysts derived from waste shell showed good reusability and had high potential to be used as biodiesel production catalysts in transesterification of palm oil with methanol.

Abstract:The transesterification of waste frying oil (WFO) with methanol in the presence of potassium hydroxide catalyst supported on Jatropha curcas fruit shell activated carbon (KOH/JS) was studied. The catalyst systems were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and the Brunauer-Emmett-Teller (BET) method. The effects of reaction variables such as residence time, reaction temperature, methanol/oil molar ratio and catalyst bed height in packed bed reactor (PBR) on the yield of biodiesel were investigated. SEM images showed that KOH was well distributed on the catalyst support. The optimum conditions for achieving the conversion yield of 86.7% consisted of a residence time of 2 h, reaction temperature of 60 °C, methanol/oil molar ratio of 16 and catalyst bed height of 250 mm. KOH/JS could be used repeatedly five times without any activation treatment, and no significant activity loss was observed. The results confirmed that KOH/JS catalyst had a great potential to be used for industrial application in the transesterification of WFO. The fuel properties of biodiesel were also determined.

Heterogeneous catalysis of transesterification using potassium hydroxide supported on coconut shell activated carbon (KOH/AC) catalyst was used to produce biodiesel from waste frying oil (WFO) and methanol. The effects of reaction temperature, methanol to oil molar ratio, catalyst bed height, reaction time, and reusability of catalyst on the conversion to fatty acid methyl ester in a packed bed reactor were studied. The results showed that increasing reaction temperature, methanol/oil molar ratio, catalyst bed height, and reaction time can enhance the conversion of WFO. The optimum conditions were a reaction temperature of 60°C, methanol/oil molar ratio 25:1, catalyst bed height 250 mm, and reaction time 2 h which yielded 86.3% of the conversion. KOH/AC could be used repeatedly for 4 times without activity loss and no activation treatment was required. The fuel properties of biodiesel were determined.
